Cascara
This deciduous tree or tall shrub is known for its medicinal bark and attractive foliage. It features oval, dark green leaves with prominent veins that turn yellow-orange in the fall. In late spring, small greenish-yellow flowers bloom in umbrella-shaped clusters, followed by purplish-black berries that attract birds and small mammals. The bark is smooth and gray, often used for its strong laxative properties. A very adaptable plant, it thrives in both sun and shade and prefers moist, well-drained soils. Ideal for woodland gardens and naturalized areas, it adds ecological value and seasonal interest with its foliage and fruit.
