Perideridia gairdneri subsp. borealis

Gairdner's yampah (northern subspecies) is a native perennial of western North America, historically valued by Indigenous peoples for its edible tuberous roots. It grows best in moist, partially shaded meadow or open woodland settings and requires careful replication of its natural habitat to thrive in cultivation. This is a specialist plant rarely found in commercial nurseries and is best suited for native plant restoration or ethnobotanical gardens.
