A sub-tropical native of Sonora, Mexico, this plant is called "white stick" in Spanish. The creamy white exfoliating bark is its most distinctive feature. Its airy form is ideal for underplanting of perennials, agaves and aloes. Weeping branches display delicate long ferny leaves. Creamy white catkin flowers in the spring are followed by brown papery pods. Palo Blanco is quite frost tender and in marginal areas will require a sheltered site with reflected heat. It thrives in full sun and prefers good drainage.
