Plant Common Name

Esperanza , Yellow Trumpetbush

General Description

The delicate beauty of this heavy blooming shrub hides its cast iron constitution. Yellow trumpetbush can stand up to the worst heat of the low deserts and the humidity of the tropics. Its only limitation is sensitivity to extreme cold. The broad range of this native spans the Americas, from the arroyos of New Mexico and Arizona southward to Argentina. Unlike other desert plants, which have silver or blue gray foliage, this shrub bears lush dark green leaves.

In mild climates it may bloom nearly all year with large bundles of lemon yellow, trumpet-shaped flowers. They disappear altogether for only a short time when the plant loses its leaves for one to three months in midwinter. Hummingbirds and bees of all kinds find their flowers irresistible.

Garden-grown specimens require perfectly drained soil and full sun. Few plants are so versatile. Yellow trumpetbush can serve as a background shrub, small tree, informal hedge or wildlife plant. It is a must for sustainable xeric landscapes, but responds well to moisture and fertilization in summer. Remove young seedpods to encourage robust and continual reblooming. Plants can be rejuvenated in early spring by pruning back the plant; mild winter frosts often kill the plant back to the roots to rejvenate each spring to form a small rounded plant.
