About Big Pod Ceanothus (Ceanothus megacarpus) Ceanothus megacarpus is a species of flowering shrub in the Rhamnaceae (Buckthorn) family known by the common name Bigpod Ceanothus. This Ceanothus is endemic to California, where its distribution extends from Santa Barbara County to San Diego County and includes most of the Channel Islands. There are two recognized varieties; var. insularis is a rare form found primarily on the Channel Islands. This shrub may exceed 4 meters in height but usually less and is covered in thick oval to nearly rectangular evergreen leaves. The leaves may be either opposite or alternate, sometimes on the same plant. The flower clusters are small and sparse and are filled with small white to pale lavender flowers with dark centers. The fruit is a large, bumpy, spherical red-green capsule about a centimeter wide. The inside of the capsule is divided into 3 valves, each valve holding a seed. The capsule dehisces neatly in two at the central band to release the seeds. This is a showy plant in early spring.
