Propagation & Germination

Stratification:
Cold/moist stratification required — 60–90 days
Germination Time:
30–90 days
Notes:
Seeds benefit from cold stratification for 2-3 months to break dormancy.

Pre-treatment: Seeds are soaked in a 1% hydrogen peroxide solution for 24 hours, rinsed, and placed in water for an additional 48 hours. Then, they are placed in warm stratification (10 °C) for 45 days, checked weekly for mold. If mold is found, seeds are treated with 1% hydrogen peroxide. Following warm stratification, seeds are layered in peat and placed into cold stratification (1 to 3 °C) for 70 days.

Establishment: Seeds should not be allowed to dry out after collection. Ripe fruits may be picked by hand, using heavy gloves, or flailed onto cloth beneath the bushes. Native to deep, conifer forests and open, rocky woods from British Columbia to Idaho and northwest Montana, south to northern CA.

ORGHPS Germination Guide: Use repeated cycles of 4°C, then 20°C for 3 months each. Germination is very prolonged. Pulpy coat inhibits germination. Remove by soaking and rinsing in clean water for approximately 7 days. Discard water. * wash off pulpy coat completely in daily detergent washes
