Cascara
$10.00
Cascara (Rhamnus purshiana) is a beautiful deciduous tree native to the Pacific North West and grows in a range from coastal British Columbia to Northern California. It likes to grow in the understory of mixed forests and prefers moist soil, but is tolerant of dry summer conditions as well. Cascara typically grows into a large bush or small tree with a mature height of 30 feet, often with multiple trunks.
Cascara is quite beautiful with its prominently veined leaves, white flower clusters, and dark smooth bark and we have planted several throughout our nursery.
Natives have used the bark from the Cascara tree to make a laxative tea, and after Cascara was introduced into modern medicine in the late 1800s, overharvesting has threatened this species.
