Pre-treatment: Clean dry seed placed in dry, cold storage following collection. Avoid heat treatment as it decreases germination.

Establishment: Fruits ripen from May through June. Seed can be rapidly collected in large quantities as fruits ripen, brown, and split open. Seed will easily spill from upright, open capsules and can be retained in open fruit capsules for 1 or more weeks after the capsule has split open. Found in Northwestern California, Sacramento Valley, Central Western California, Southwestern California, Oregon, n Baja California.
