Yellow Bells, or Esperanza, impresses everyone with its large clusters of golden yellow, trumpet-shaped flowers, bending the branch tips into arches with their weight. The profuse, 1 to 2-inch-long blossoms attract hummingbirds and butterflies with their fragrance and nectar. This heat-tolerant, drought-tolerant shrub is related to our Desert Willow, while its lush deep green leaves resemble those of elderberry. Blooming occurs in flushes from late spring into fall, producing 8-inch-long string bean-like pods. Prune or pinch off old flowers and seedpods for repeat blooming and to maintain a bushy plant. Several cultivars are available with various flower colors and plant sizes from 3 to 25 feet tall. While all Yellow Bells love heat, most have frost-sensitive leaves, but their roots survive much colder temperatures. Cut back annually when new growth starts in spring to remove frost damaged foliage; plants will recover quickly. Beautiful as an accent, container plant around patios, or planted in masses in beds and borders.


Mid-September to mid-October starts the most important planting season of the year

  • Plant native and drought-tolerant plants; warm soils helps new plants develop deep roots before summer, reducing water needs during new plants’ entire two to three year establishment period
  • Fall opportunity to transplant Joshua trees and yuccas from September to October
  • Reduce water to cactus and succulents to prepare them for winter rest and protect against frost damage
