Narrowleaf yellow trumpetbush is a fast-growing native shrub or small tree of the desert Southwest, prized for its brilliant clusters of yellow trumpet-shaped flowers that attract hummingbirds and butterflies. It thrives in full sun with well-drained soil and is highly heat-tolerant, making it an excellent choice for xeriscape and low-water landscapes in warm climates. Once established, it requires minimal irrigation and can be lightly pruned in early spring to maintain shape.
