What You’ll Learn
What Is Norfolk Island Pine?
Araucaria heterophylla , or Norfolk Island pine tree , as it is more normally known , is a coniferous tree that is enjoy for its endearing evergreen foliage and symmetrical shape .
This tree also go bad by the names “ business firm pine , ” “ star true pine , ” “ Triangulum Sir Herbert Beerbohm Tree , ” “ Australian true pine , ” or “ Polynesian true pine . ” Formerly , it was taxonomically relegate asA. excelsa .
The other plebeian name you may be most intimate with , though , is “ living Christmas tree . ” It ’s also often called simply “ Norfolk pine . ”
This conifer has a symmetrical form with widely space layer of whorled branches hold out horizontally from a straight trunk .
The species name “ heterophylla ” imply “ unlike leaf ” and afford a cue to one of the quirks of this tree diagram .
Its younger leaves look like needles , while its more mature parting look more like scale . Both types of leaves can be regain growing on the tree at the same metre .
Mature leaf are small , a fourth of an inch long , and scale of measurement - like . They can be lancelike or triangular .
Juvenile leaves , on the other hand , are half an inch long and may be mistaken for fir tree or spruce needle .
Unlike some coniferous tree whose acerate leaf are sharp and prickly , this plant ’s foliage has a wonderfully soft and fine texture – except , that is , along the bole .
The acerate leaf that emerge from along the gray - dark-brown luggage compartment of this tree are not to be piddle away with , so watch your digit when relocating this conifer !
A unexampled layer of branches emerges from the top of the Sir Herbert Beerbohm Tree each year .
The branches radiate out symmetrically , giving this evergreen conifer a Great Pyramid - like shape .
If yours does n’t have that distinctive pyramidal flesh , there ’s a reason for this . Those sell in garden centers oftentimes check more than one sapling per pot , giving them a bushier and less symmetrical appearance .
When these trees grow out of doors , at about ten to fifteen years old , they begin producing large cones that arrest edible seeds similar to pine nut .
However , despite their appearance and their pinon - like seeds , these evergreen trees are not really pine .
Cultivation and History
Despite the rough-cut name , Norfolk Island pines are nottrue pine . They are members of the Araucariaceae fellowship , an ancient house of cone-bearing trees that were widespread throughout the Earth when dinosaurs roamed the Earth .
But the same events that caused the dinosaurs to go nonextant also caused most of the species in this family to choke .
However , forty - one know species in this kinfolk remain , most of them in the Southern Hemisphere .
They are look at “ relicts ” or life fossils , since the majority of their relatives are nonextant . Among these living fossils is the subject of our article .
Another one of these living fossils is a Sir Herbert Beerbohm Tree you may be familiar with – the monkey puzzler tree , A. araucana , which is also an evergreen plant coniferous tree .
A indigene of the lower gradient of the Andes Mountains , the monkey puzzle tree is more cold - hardy than the subject of this article .
While closely colligate to this South American conifer , A. heterophylladoes not spring up natively near the monkey puzzle tree . Like the absolute majority of its live relatives , A. heterophyllaoriginated in the South Pacific .
In the subject of this tree , it originate on a little island that gives it its name – Norfolk Island , a district of Australia that is situate between Australia , New Zealand , and New Caledonia .
Norfolk Island became known to Europeans after Captain Cook voyaged to this area on his second South Pacific ocean trip , in 1774 .
He believe the tree diagram ’ perfectly neat trunks would be desirable to use as masts for ships , but this turned out not to be the pillow slip – despite their coastal pedigree , these tree diagram are not as live to high wind as one might think .
These solar day , this evergreen plant conifer is grow as an ornamental tree in subtropical , strong temperate , mid temperate , and Mediterranean region , where it can potentially grow to be two hundred feet marvellous .
In the US , it can be grown in the landscape inUSDA Hardiness Zones9 to 11 , including Hawaii , and parts of California and Florida . The marvelous one in the US was guess to be 115 foot tall and approximately 115 yr erstwhile in 2019 .
Along with its exercise as a landscaping feature , the Sir Henry Wood from these trees is prized for woodturning , and is used in Hawaii and other locations where it grow for the creative activity of artisanal wiliness .
For those of us who do n’t live in such clime , Norfolk Island pine is produce indoors as a houseplant , where it normally maxes out at five to eight feet tall .
Propagation
If you want to give propagating this industrial plant a try , you have a few different pick – spring up clones from film editing , atmosphere layering , or growing new plants from come .
I ’m going to focus on the two most accessible method acting and leave air travel layer out of this word for now – but perhaps it will show up in a future article .
countenance ’s begin with growing new plants from seeds .
From Seed
If you have ever buy one of these evergreen plant coniferous tree , it was most likely grow from a come – that is the primary method used to propagate these plant commercially . This make them slightly singular among houseplant .
Many houseplant – such as prayer plants , African violets , snake in the grass plants , andorchids – are typically propagated vegetatively , through partitioning or cutting , score the resulting fresh plantsclonesof the parent plant .
With living Christmas trees , however , each plant grown from a ejaculate is a true person with its own unparalleled genetic physical composition .
Now that I have finished waxing poetic about the scientific curiosity of propagation by seed , shall we get on with the how - tos ?
First , you ’ll want to get your hands on some Norfolk Island pine tree seed .
Or , if you have plans to grow these and lapse them around as endowment , you may want to hold an entire pinecone from one of these magnificent trees . One pinecone hold dozen of seed capsules , each of which bear a exclusive seminal fluid .
Use seeds that were harvested recently , since they quickly lose their viability – after just three month in storage , about one-half of the seeds will lose the ability to sprout .
You ’ll also want some small glasshouse pots , some sterile pot grime or soilless growing culture medium , and a plant mister . If you ’re reusing old nursery lot , make certain to sterilize them first .
make full the nursery pots with soil , leave one inch of space below the rim at the top .
If you are ferment with a cone , remove the seed capsules if they ’re still attached .
Place a seed space capsule on the surface of the dirt in each of your nursery potentiometer , but do n’t cover it with soil .
This surface - sowing technique isrecommended by R. T. Poole and colleaguesat the University of Florida ’s Institute of Food and Agricultural Sciences and the Central Florida Research and Education Center at Apopka .
And you may want to take a trick from commercial agriculturalist of these plants – they often plant several saplings in one pot to give the plant a fuller , bushier appearance .
After surface - sow your source capsules , spray the soil with a industrial plant mister to keep the top inch of the ground moist but not muddy .
If you live in a teetotal climate like I do , you may want to cover the green goddess with a humidity collapsible shelter – a transparent charge plate baggy deem in lieu with a rubber stripe to help keep the humidity high . Or you could place your seedlingsin a terrariumor greenhouse .
put the pots where the seeds will be exposed to raft of bright light – they need brightness to germinate – and stay at a temperature of 70 - 80 ° atomic number 9 . You may take a warmth mat to help keep up this temperature .
The Jump Start heat Master of Arts in Teaching is sized for a windowsill , and isavailable at Arbico Organics .
rise Start Windowsill Heat Mat
Your seeds should sprout in 10 to 21 day .
Once the seeds have sprouted , you may murder them from their humidness tents . Keep your young saplings at a temperature between 60 and 90 ° F while they are getting established .
As your saplings begin to grow , get going to water ordinarily , whenever the top of the dirt dry out out . Your saplings should be ready to pot about ten week after sprouting .
It will take at least two years of growth before your sapling sizes up . As need , you should be prepared to repot your survive Christmas tree sapling .
From Cuttings
Another method of broadcast this species is by rooting a cutting from the parent flora . However , this process is not as soft as propagation via cum .
Here ’s the job :
If you take your cut from a limb , this carving is not conk out to farm upwards like a tree diagram – it ’s go to spring up like a ramification .
So , if you desire a new plant life that will grow upright like a tree , you ’ll have to take a cut from the growing crest . The hitch here is that there ’s onlyonegrowing crest per plant .
If you reduce the grow tip , it could potentially kill the works , or at skillful , cause it to recede its proportionate shape .
However , there is one case in fussy in which you may want to perform this process anyway : if you have a survive Christmas Sir Herbert Beerbohm Tree that has outgrown your home , but which you need to uphold for sentimental reason .
fundamentally , you ’re keeping apartof the old works live , if not the whole .
Some gardeners report that cutting back the parent flora and letting it resprout has work for them .
But before you grab your pruners and start hacking by at your Sir Herbert Beerbohm Tree , let me warn you that root cuttings is n’t always successful . The cutting needs to be defend in quick soil and at a high-pitched level of humidness .
If you resolve to give this a effort , use a heat Master of Arts in Teaching like I cite above .
On the other hand , if you are the data-based type like I am and want to try rooting a cutting from a leg just for merriment – go for it . This might be good practice to try first if you really desire to try on rooting a film editing from the growing tip later .
In fact , can we all make a pact that nobody is going to try taking a cutting from the growing tip before practicing with a branch first ? Okay , ripe . Now , allow ’s get to our recitation sitting .
meet your supplies – you ’ll need a pair of sharp , sterilized trimmer , some sterilized growing mass medium , one small nursery lot per carving , and a sprayer bottle .
fill up your greenhouse grass with growing mass medium , leave an in of quad at the top below the brim .
With your pruners , take a four- to five - in cutting from one of the offshoot – this is a right opportunity to shape up your tree if it has any branches that are longer than the others .
Remove the needle from the bottom inch or two of the cutting .
To meliorate the chances of successful rooting , you could apply a rooting hormone to the gash conclusion , such as Olivia ’s Cloning Gel , available at Arbico Organics .
Olivia ’s Cloning Gel
Make a hole in the growing medium and insert the cutting , then use your atomizer bottle to wet the grow culture medium enough so that it is dampish but not swampy .
Cover your potted newspaper clipping with a gauze-like moldable bag and stop up it with a galosh dance orchestra to create a humidness tent . Alternatively , send your cuttings in a terrarium or glasshouse .
Check your cutting day by day , and water with your mister when the grunge surface dry out . irrigate with a Mr. is a serious direction to prevent the dirt from becoming waterlogged .
Growing one of these evergreen conifers from a cutting is a wearisome process , and you ’ll require to practise some solitaire while at the same time remember to check in on it every Clarence Day .
As such , this might not be the proficient experiment to do with kids or beginning gardener who could apply a boost in the form of quick results .
Once the cutting is root , you will feel electrical resistance if you set about to – gently – tug it out of the potting soil .
Rooted cutting can be transplanted into containers and cared for as houseplant .

How to Grow
These plants are fairly forgiving houseplant as far as care goes .
However , to keep your plant face its near , and to keep it in your home as long as possible , it ’s wise to learn some of the good tutelage act for this conifer .
Choosing a Plant
Some Norfolk Island pines are spray with green paint or sparkle at the holidays – the time of year they are most widely useable .
If you want to keep your Sir Herbert Beerbohm Tree on as a long - terminal figure houseplant , make indisputable you purchase one that is in its natural land , sanspaint or glitter , which can interfere with the plant ’s ability to photosynthesize .
Here are a few other thing to look for :
Next up , it ’s all about giving your novel acquisition everything it needs to thrive .
Light
When you bring your living Christmas tree home , choose a in effect spot for it to live . These Tree will permit full sun to partial shade , but when grown indoors , they do best with plentifulness of bright , indirect lightness .
If you could ply your tree diagram with a few hours of direct morning sun , followed by bright , indirect illume the eternal sleep of the solar day , it will be extremely glad .
I have mine situated several feet from a bright south - facing window and also a few foot from a westerly window . It seems to be quite broad of this place – but during summer , when the Christ Within from these two window is hottest , I use sheer curtain to cover both , making the spark more diffuse .
If you want to keep your Norfolk Island true pine situated in full sunlight , be sure to transition it gradually to such vivid twinkle .
question if you could home your plant in a scurvy brightness site ? As mentioned above , this species will tolerate partial tincture , but with less light they tend to become leggy .
The more bright , indirect lighting you could give your plant , the more this will help oneself to keep its acerate leaf a dainty , bright unripened color .
Too much verbatim Sunday , on the other helping hand , can leave in foliar bleaching – and your tree ’s needles can take on a yellow hue .
And to keep your flora from becoming crooked , give it a after part round every week , so that it mother sunshine from all angles .
If you do n’t have a lot of promising lightness amount into your base , you may need a develop light to serve your house pine get sufficient luminosity .
To check more , read our complete pathfinder on thebest grow lights for houseplant and seedlings .
Temperature
One of the mistakes that plant parent make with this houseplant is to recall that since they are conifers , they must be just as cold-blooded - hardy as the firs and spruce that produce outdoors .
Many a living Christmas tree has met its dying when go forth on a deck of cards or terrace after temperatures start to cool .
So retrieve , these plants are native to warmer climate , and ideally you should keep them above 50 ° atomic number 9 . Exposure to temperatures below 35 ° F can kill them .
When kept in mediocre indoor conditions , these plants will do just fine – they prefer a range of 60 to 72 ° F during the daylight , and a slightly cool temperature at night .
Just make certain you avoid placing your know Christmas Sir Herbert Beerbohm Tree in a draughty location , such as near an exterior door or draughty window .
If you give your Norfolk Island pine outdoor time in summer , be cognisant that this may make it develop faster . And remember to bring it back indoors when the atomic number 80 falls into the 50s .
Water
While living Christmas tree diagram prefer moist land , they are quite drought resistant , as my own Norfolk true pine can attest to .
After a stressful move one year , my plant was neglected and it was not watered for ( I ’m ashamed to say ) at least two summer month , if not prospicient .
Its phonograph needle started to ferment brown – including those of its growing tip – and my hubby and I both thought it was a goner .
But before we relegated it to thecompost down , we decided to see if we could resurrect it . And surprisingly , it rally ! It soon began putting out novel , bright green foliation and look quite happy and undaunted .
But just because these plant do have some unlearned drought tolerance does n’t mean you should abuse them – irrigate them when the top inch of soil feels ironic .
If you are an overeager plant caretaker , who tend to overwater rather than underwater , go easy on your living Christmas tree . These plants do opt damp soil , but not soggy filth .
Keeping soil moist but not soggy depends not only on your lachrymation technique , but also on the potting soil used . ( I ’ll get to that a small later on . )
When it ’s time to irrigate your living Christmas Sir Herbert Beerbohm Tree , pour water evenly over the grease until it start to run out of the bottom of the gage .
If your tree has a saucer under it , verify to remove any water that die hard into it . Like most other houseplant , Norfolk pine does not care to have soaked foot .
unseasoned plant will require more frequent watering than more mature trees .
How often you ’ll need to piddle will vary look on the age of your Sir Herbert Beerbohm Tree , and it will also vary from household to home , depending on how warm your home is , how much brightness level the Sir Herbert Beerbohm Tree is exposed to , and how humid your melody is .
So get to know your works – adhere your finger into the filth and when the top in is dry , this is a honest time to urine . prove to get into a modus operandi so that you could invalidate abandoning your tree diagram to ignore and inadvertently testing its resilience , like I did with mine .
If you ’re not certain if you ’re water enough , look out for browningon the tips of offshoot – this often means the plant is being underwatered .
And once the mean solar day bulge to nerveless and winter go far , your Norfolk pine should require pee less frequently .

Humidity
A. heterophyllaappreciates a routine of extra humidness – commonly more than is available in our home base when they are heat up in the winter – preferably 50 percent or higher .
If you have to deal with dry breeze , either in the wintertime or all year long like I do , there are several different ways you could increase humidness to keep your plant happy and healthy .
If you have other houseplants , you may group it with some plant pal . This proficiency will help raise the relative humidness around all of the plants .
You might also consider setting up a humidifier nearby ( which will also help your nasal passages , by the way , if your nursing home is very dry ) .
Another option is to place your flora on a tray full of pebble . fill up the tray with water , but make certain the water is n’t high than the pebbles to head off letting the plant wick up too much piss through the soil .
you’re able to make your own pebble tray , or buy one . There are also humidity tray available that body of work with a grid rather than pebble , such as this one from Humidi - Grow .
It is 13.5 by 10.5 inches , and it isavailable via Amazon .
Humidi - Grow 13.5 ” x 10.5 ” Humidity Tray
You might also require to obnubilate your plant day by day with a nebulizer bottle to help increase humidness . Just ensure to spray it in the morning , to reduce the chances of fungous or bacterial growth , which are more probable to be a job when foliation is cool and sozzled at night .
If you already live in a very humid climate , you ’ll probably want to skip adding redundant humidity to your living space .
But if you have no clue as to what the level of humidity is in your home and need to monitor it to make trusted you ’re keep your houseplants comfortable , you’re able to use a hygrometer , a pecker used to measure comparative humidity .
Mini Hygrometer and Thermometer

Fertilizer
While fertilizing houseplant is generally a skilful idea , to provide nutrient that they are n’t able to reap readily since their access to stain is reasonably limited and often easy depleted , in the shell of Norfolk Island pines , you may desire to go easily on the amendments .
Here ’s why :
If you fertilize frequently , your Sir Herbert Beerbohm Tree will grow more quickly . Once it grow enough , it will eventually size out of being a houseplant – unless your home is equipped with highly high ceiling .
Fertilizing double a year may be plenty to provide your plant with the nutrients it needs .
When you do opt to fertilise , you should do so only when the plant is actively develop , from more or less March through September .
you could utilize a general - purpose houseplant plant food for this plant , which is not as sensible as some other houseplants to the salts that can pile up from fertilizing .
Or you may take a more natural , organic approach , like I do , by using worm compost afternoon tea to feed your industrial plant . you’re able to make your ownworm composttea from your worm cast .
But if you have n’t started keep worms ( yet ) , you might want to try this bang-up way to make worm compost teatime instead . TeaDrops are tea leaf mailboat turn back dry worm compost that are ready to apply .
TeaDrops Organic Houseplant Fertilizer
You soak them in way temperature water , and then use the result “ tea ” to both water and fertilize your houseplants .
You ’ll retrieve a pack of 16 worm compost tea leaf packet from theEarthworm Technologies Store available via Amazon .
Growing Tips
Pruning and Maintenance
One of the nice things about these works is that they are sincerely low maintenance . However , it will be helpful to know a few tips for deal for your flora during the holiday , pruning , and repotting .
Holiday Care
The average houseplant care pathfinder in all probability does n’t include tips on how best todecoratethe plant .
But since Norfolk Island true pine can be used as stand - in Christmas tree diagram , I think it best to point out a couple of additional care item related to the vacation .
The outgrowth of these trees are n’t as sturdy as those of a Frasier fir , and wo n’t stand up well to a cloggy load of decorations – so set your Sir Herbert Beerbohm Tree trimming to Christmas ornaments that are lightweight .
fore , ribbons , and lightweight methamphetamine ornament make honest choices .
And while your living Christmas tree might look charming nestled next to the fireplace as part of your vacation decor , this plant wo n’t treasure the temperature extreme that can occur when a fire is roaring .
Plus , when located on the outside wall of a home , chimneys can cause dusty draught . So make certain to put this coniferous tree out from fireplaces to debar not just the heat , but also possible cold draft .
Pruning
The scurvy branch of these houseplant will flex brown and pall as these plants raise . This is a normal mental process – you’re able to polish off the lower dead branches with a pair ofgarden snips or pruners .
Also , while you work on get your watering agenda down , your tree might show its displeasure at receiving deficient water by have a branch peak or two go browned . Feel free to clip these off as well .
However , it ’s best to quash cut greenish increment since this can , as one author at theRoyal Horticultural Societyputs it , “ spoil the shape of the tree diagram . ”
Repotting
As with fertiliser , your choice to repot this plant life – or not – will contribute to the speed with which it grows , and the sizing it ultimately attains .
If you ’re desire for a immense tree to make an impact in a large outer space , repot your Norfolk Island pine every year or two , moving it up to the next sized pot .
On the other paw , if you want to keep your living Christmas tree at a more petite size , do n’t repot it into a larger container .
Instead , you could replace the works ’s dirt with a new soil mix to refresh it if you wish , but return it to the same sized potentiometer .
No matter how often you repot , ensure the flora ’s pot has drainage holes . Otherwise , its source will become waterlogged and the flora can die from root rot .
There is another case in which repotting may be beneficial to your plant – if your living Christmas tree has been overwatered in the past , repotting it in a fresh batch of potting soil and trimming any rotten roots off will be good .
This plant can grow in dirt with a slightly acidulent , neutral , or somewhat alkaline pH. It grows natively in a sandy , chalky loam , and is tolerant of piquant territory due to its coastal origins .
When repotting , use awell - draining potting mixthat has some sand in it – the grit will both help with drainage and provide stability , to prevent the automobile trunk from tilt .
I like Soil Mender 109 Potting Mix for this purpose . It contain cocoanut coir for drain and piss retention , sand for drain and stability , and it ispeat - destitute .

Managing Pests and Disease
Part of a live Christmas tree ’s no - drama care routine is that it is n’t very susceptible to blighter or disease . However , it ’s upright to be on the lookout for certain insects and pathogens – just in case .
Insects
While insects may never be a problem for your plant , here are the most vernacular ones to be aware of :
Mealybugs are a frequent pest of houseplants and they can , on occasion , attack your Norfolk Island pine just like they can infest yoursucculents .
Easy to recognize , mealy bug come out with a telltale white , cottony visual aspect on your tree – particularly on its branches .
When these pests are present , they will bond to your tree and suck nutrients from it , weakening it , causing the tree diagram to become stunt , and finally killing parts of it .
you’re able to control a minuscule mealybug plague by rubbing them away with a paper towel damped with rubbing alcohol .
For more severe problems , neem oil can be used . Just follow the producer ’s counselling for applying this intersection .
Monterey Neem Oil

Scale looks like raise brown spots on your plant – they do n’t reveal themselves very easy as insects .
Like mealybugs , scale of measurement will suck nutrients from your houseplants , de-escalate them and eventually vote down them .
To handle scale on these plant life , you may use the same technique as described for mealybugs – depending on the severeness of the plague , either use rubbing inebriant , or apply neem oil .
Find more tips on combating ordered series insects here .
Spider touch are also frequent houseplant pests , and they can set on Norfolk Island pines as well . wanderer speck tend to be more of a problem in winter when the air is dry – yield you another good reason to supervise the relative humidness around your plant .
You may notice dapple yellow spot on your Sir Herbert Beerbohm Tree ’s foliage . With wicked plague , you ’ll start to see vane surrounding the foliage .
wanderer speck also sop up nutrients from your houseplants , dampen them , and potentially kill them .
To treat a spider pinch job , first wipe them forth with a damp report towel . Then treat as need with rubbing alcohol or neem oil .
Learn more about controlling wanderer mites here .
Disease
With good care , you are unbelievable to encounter disease in your living Christmas tree . If you comment any discoloration in your plant ’s foliage , here are a few problem to look for :
Anthracnose is a disease cause by a fungal pathogen , Colletotrichum derridis .
When your living Christmas tree is infected with anthracnose , you ’ll notice dead needles . On closemouthed review , you ’ll see black areas on the needles , which is the fungus itself .
Fungi flourish in moist conditions , so ensure to water your tree diagram at the filth grade – not overhead . And if you mist , do this in the morning so that water does n’t accumulate on foliage over night when temperature are cooler .
Neem oil is an organic fungicide that can be used to care for anthracnose .
Some of the signs of stem rot let in stunting , wilting , and dying arm .
If you have a Norfolk Island pine tree that is spring up in soil that drain ill , in a kitty without drainage holes , or if you simply gave it a little too much erotic love ( i.e. urine ) , antecedent rot might be a problem .
When your plant ’s roots pose in waterlogged grease for too long , they ca n’t get atomic number 8 and will start to give-up the ghost – which results in them not being able-bodied to enrapture water system to the foliage . Ironically , this can cause the plant to perish from dehydration .
In addition , bacterium and fungus kingdom can proliferate in this waterlogged surround , add vilification ( and further contagion ) to injury .
To treat root rot , correct whatever is going on :
If the soil does n’t drain well , replace the soil . If the pot has no drainage holes , switch out your toilet .
If replace its soil looks like the best choice , do n’t move your plant life up to a braggy pot size . While repotting , you’re able to trim off any rot roots from your plant – just recall to use sterilized pruners for this functioning .
Have you had a pest trouble on your Norfolk Island pine tree recently ? Aphids , exfoliation , and mealybugs secrete honeydew melon , which can give a foothold tosooty mold , another fungal outlet .
To process sooty mold , often cause by several different specie of fungus kingdom at once , you may apply neem oil , the same production you would utilize to get free of the little pests that make it in the first place .
Best Uses
A vernal Norfolk Island pine that is one to two feet tall can be used to adorn a desk , tabletop , or mantlepiece . A larger tree can be a unspoiled alternative to a cut Christmas Sir Herbert Beerbohm Tree – and you wo n’t have to put it on the curb when the holidays are over .
And like many other evergreen coniferous tree , this plant can be turned into a bonsai .
If you have cats or Canis familiaris , you’re able to take this tree diagram into your house without worrying about it being a source of danger to your ducky – consort to theASPCA ’s Toxic and Non - Toxic Plantslist , it is nontoxic .
