During the cretaceous period , a group of plants grow called angiosperm . These plants were characterized by a raw evolutionary development : flush . Flowers survive to help angiosperm reproduce . This generative scheme was successful enough that there are more flowering plant on Earth than any other character of plant . They are also the most various grouping of industrial plant .
Asters
The dependable aster is a perennial , a kind of flowering plant that survive at least three years . Once perennials start out blooming , they can bloom every twelvemonth as long as conditions are correct for them . aster like full sun and good soil . They unremarkably bloom in fall , though hybrids exist that efflorescence in spring .
Forget-Me-Nots
Shorter - lived than perennial are biennial . The bury - me - not , for good example , is a biennial in some surroundings . In colder areas , block - me - nots exist for only two years . Modest forget - me - nots like a bit of shadiness and do n’t like ironical soil . bury - me - nots are often light blue , but also issue forth in pinkish , white and darker gamy miscellanea .
Morning Glory
good morning aureole are annuals , the shortest - lived angiosperm , which live only one season . Morning aureole are properly named since the shy flush only wish to open in early cockcrow , though some dawn resplendence have been developed that bloom longer . The morning gloriole open across-the-board , with blossoms as big as 8 inches wide . The plant vine , grow in full sun up to 10 foot mellow if you give it the support of a treillage or drawing string .
Lilies
The lily is a complete flower , mean it has the four most basic parts of a flower : flower petal , sepals , virile parts to make pollen and distaff part to make yield and seed . Lilies , which come out from bulb , grow to be 2 to 8 feet tall . They sometimes need a interest for support . The lily does n’t involve high - quality ground ; indeed , chip in lilies good soil can create weak stems .
Calla Lilies
With no sepal or petals , the calla lilly is a " naked bloom . " It is also " uncomplete , " as are any flowers that do n’t have all four basic parts . The part of the calla lily that many people think of as a flower is actually a modified leaf . It emerges from the stem , furled funnel - similar , frisk chickenhearted , blank , pink or red people of color . Some calla lilies even have a light odour . The plants grow from rootstock , a kind of underground stem .
Roses
In flora the rose is think " perfect , " because it has both virile and female part – all the necessities for reproductive memory . A enchantment with roses has go to an abundance of type – wax chaparral , mounting rosebush , long - stem rose , miniature roses and roses in many shades of colour .
Begonia
weak flowers like the begonia are either manly or distaff . This being the case , both manlike and distaff peak are needed for successful reproduction . The begonia plant adopt care of this by growing both form on each industrial plant . Plants that do this are call monoecious . Dioecious angiosperm ask at least two plants to accomplish reproduction . begonia are perennials , but since they do n’t do well in the common cold , they are often used as annuals in northern climates . They can also be used as pot plants and some varieties are appropriate for hanging basket .
