Many flowering plants feature blooms that live for one day only. While this may seem undesirable, in reality, the plants have enough buds for a new flower to bloom each day, creating the impression of an ever-flowering plant. For that reason, these attractive plant choices are highly popular with home gardeners who want a display of seemingly continually blooming flowers.
Tropical hibiscus plants (Hibiscus rosa-sinensis) are flowering shrubs or trees. These differ from perennial hibiscus plants in that the flowers of the tropical hibiscus bloom for only one day. Most are also warm-climate plants only and grow best in United States Department of Agriculture (USDA) zones 9 and 10.
The flowering habits of these showy plants, which feature large, brightly colored blooms, can vary by cultivar. Some hybrids of the tropical hibiscus, for example, have flowers that bloom for two or three days. Still, most tropical hibiscus plants have flowers that bloom for only one day, according to the University of Illinois.
Virginia spiderwort (Tradescantia virginiana) is a perennial plant that grows wild in the meadows and forests of the eastern portion of the United States. This understory shrub thrives in the dappled shade of deciduous trees and features clusters of small, purple flowers that open in the morning and wilt by the time the sun sets.
Daylilies (Hermocallis spp.) are hardy perennials. Highly desirable for their ease of care and spreading habit, these flowers bloom for only one day, as their common name implies. Each tall, slender flower stalk is lined with buds, each of which will open for a single day. The large flowers take turns opening, ensuring that there is always a flower on display, even during the heat of midsummer.
There are so many species and cultivars of daylilies (more than 38,000, according to the University of Vermont) that it is easy to find one that will thrive in almost any climate. In general, most types of daylilies grow best in USDA plant hardiness zones 4 through 10.
