Descriptions
Uinta Basin Hookless Cactus
A rare, small, globular cactus with prominent hooked spines and beautiful, disproportionately large flowers. This is a federally listed threatened species found only in the Uinta Basin.
Ulmo
A large evergreen tree prized for its abundant, fragrant, cup-shaped white flowers. The flowers are a major source for a distinctive and highly-valued honey in its native Chile.
Umbrella Magnolia
A deciduous tree known for its enormous leaves arranged in a whorl resembling an umbrella. It produces large, fragrant, creamy-white flowers after the leaves fully emerge in spring.
Umbrella Plant
A bold perennial for moist, shady areas, featuring large, round, umbrella-like leaves. It sends up naked stalks topped with rounded clusters of star-shaped pink or white flowers in early spring.
Umbrella Wort
A native wildflower, also known as Wild Four O’Clock, with smooth stems and clusters of small, trumpet-shaped, magenta-pink flowers that typically open in the late afternoon.
Unicorn Plant
An annual known for its sticky foliage, showy, orchid-like flowers, and unique, long-beaked seed pods that give it its name. The flowers are bell-shaped with purple spots.
Upland Cotton
The most widely planted species of cotton, this plant is a shrub that produces showy, hibiscus-like flowers. The flowers open white or yellow and fade to pink or purple after pollination.
Upland Ironweed
A tall, native perennial wildflower that thrives in sunny spots. It is notable for its intense, deep purple, fuzzy-looking composite flower heads that bloom in late summer, attracting butterflies.
Upright Virgin’s Bower
A non-climbing, herbaceous clematis species that forms a bushy clump. It is covered in a profusion of small, fragrant, star-shaped white flowers in early summer, followed by silvery seed heads.
Urn Plant
A popular bromeliad houseplant with a rosette of silver-banded leaves. A large, long-lasting pink flower spike emerges from the center, bearing small, short-lived violet-blue flowers.
Ursinia
A cheerful, daisy-like annual with finely divided, feathery foliage. It produces a profusion of brightly colored flowers, often with a distinct dark, purplish ring at the base of the petals.
Uruguayan Firecracker Plant
A perennial with velvety, silver-gray leaves and striking, tubular, orange-red flowers that are highly attractive to hummingbirds. It spreads by underground runners, forming a dense clump.
Uruguayan Potato Tree
A fast-growing small tree or large shrub with large velvety leaves and impressive clusters of large, potato-like flowers. The flowers open a deep lavender and fade to white over several days.
Utah Agave
A small, spiky agave forming dense rosettes. After many years, it sends up a tall flower stalk bearing clusters of bright yellow flowers, after which the parent plant dies.
Utah Penstemon
A vibrant wildflower native to the desert Southwest. It produces tall spikes of intensely colored, tubular flowers that are a magnet for hummingbirds and bees in its arid habitat.
Utah Serviceberry
A deciduous shrub or small tree found in dry, rocky areas. In spring, it’s covered with clusters of delicate, five-petaled white flowers before the leaves fully emerge, later producing edible berries.
