When you live in an area that battles drought every year, and has strict watering restrictions, creating a landscape that is easy on the eyes is difficult. Drought tolerant flowering trees help the homeowner conserve water and keep the landscape colorful. The trees, if strategically planted, also help keep the house cool by blocking the sun's rays.
The trumpet tree (Tabebuia caraiba) grows up to 25 feet in height with a spread of up to 15 feet. Its silvery foliage is furrowed and the branches are contorted. The tree produces golden yellow trumpet-shaped flowers and pod-shaped fruit that is up to 12 inches in length. The pods tend to stay on the tree and do not cause a litter problem. The trumpet tree thrives in U. S. Department of Agriculture Plant Hardiness Zones 10 and 11. The trumpet tree is highly drought tolerant and grows in light from partial shade to full sun. As long as the soil is well drained, it can be clay, sand, loam, acidic or alkaline.
The geiger-tree (Cordia sebestena) is a highly drought tolerant evergreen that grows up to 25 feet in height with a crown of up to 25 feet. The leaves are large, growing up to 7 inches, and feel like sandpaper. It produces dark orange flowers that are about 2 inches wide. After the flowers are spent, the tree produces small, pear-shaped fruit. The geiger-tree thrives in USDA Zones 10B through 11. It tolerates partial shade through full sun, and is pest and disease resistant, making it a low-maintenance landscape tree.
Golden Rain Tree
The golden rain tree (Koelreuteria paniculata) grows to a height of 40 feet and is highly drought tolerant. It produces showy, fragrant, yellow flowers. The seedpods are papery-like and lantern-shaped. Each pod contains three seeds. It is mostly pest-resistant, but does attract red-shouldered bugs (Jadera haematoloma). The red-shouldered bug does not damage the tree, but it can damage foliage on other plants.
