Flowers That Bloom Daily

The assortment of nature isn’t quite as chaotic as it may seem. Flowering, as an example, was determined over millions of years of trial and error in which species which did not adapt to changing distances and evolving life forms died and plants which adapted to changing states survived. Since plants evolved under different states, they may produce blooms that last for several days or for just one.

Plant Speak

Plants do not only produce blooms for the sake of appearance, they blossom to attract the insects and animals that move pollen to their stigmas, fertilizing eggs which become seeds out of which grow the next generation of crops. Throughout time, plants have evolved to time their behaviour to the 24-hour days of the pure world, referred to as the circadian clock. Flowers that stay open only 1 day, like many bearded irises (Iris germanica), pumpkin (Curcubita pepo) blossoms, riparian African irises (Dietes spp.) And even weeds like dandelions (Taraxacum spp.) , frequently generate a string of flowers that open in succession, each booming for only one circadian cycle. Bearded irises grow through U.S. Department of Agriculture plant hardiness zone 10 and African irises grow in USDA zones 8 through 11, but won’t tolerate freezing temperatures.


Chinese hibiscus (Hibiscus rosa-sinensis), also referred to as tropical hibiscus and rose mallow (H. moscheutos) are shrubs which both produce flowers that last just one circadian cycle. They produce new blooms every day over the entire summer. Although Chinese hibiscus is temperature-sensitive and is customarily grown in containers which can be moved inside during cold weather, rose mallow is cold hardy and, given enough water, grows outdoors all through the year. Both produce big, papery blooms in whites, pinks and brighter colors like scarlet and lemon-yellow. Rose mallows are hardy in USDA zones 5 to 9 and Oriental hibiscus rise in zones 9 to 11.

Morning Glory and Moonflower

Morning glories (Ipomoea nil and I. purpurea) blossom in blue, purple and scarlet on yearly vines that grow up to 20 feet long and peak out from beneath arrow-shaped leaves. Flowers blossom daily, in series, all year long. Tissue-thin, trumpet-shaped flowers cover the vines, stretching open as the sun warms the air and twisting closed as it places. A nocturnal species, moonflower (I. alba), also flowers daily, opening at sunset instead of at the morning.

Day Lilies

Day lily (Hemerocallis spp.) Branches, known as scapes, can hold from a few to dozens of buds. Named for their flowering habit, day lily cultivars range from rugged tawny daylilies (H. fulva), called ditch lilies for their adaptability to roadsides, to fancy tetraploid hybrids which need regular fertilization. The plants reproduce rapidly and can be divided to make new plants every three to five decades. Lily-type blooms start at the top of the scape and blossom in every shade except blue. Day lilies grow from USDA zones 3 through 9, but some newer varieties developed for southern conditions grow through station 10.
