Oregon Yampah

A perennial species of flowering plant in the carrot family, Oregon Yampah can be variable in appearance, but has lacy, delicate leaflets, reaching 0.3-3 feet tall, and about one foot wide.

Yampah grows from tubers, and dies back after blooming, so be sure to remember where you’ve planted it! In summer, each plant sends up a green to waxy-gray stem reaching up to three feet tall, and topped with a compound umbel of clusters of tiny white flowers that are excellent for pollinators!

Plant in full sun along the coast, in companion with other woodland opening species like California Bee Plant, Woodland strawberry, or California Fescue.
