Propagation & Germination

Stratification:
Cold/moist stratification required — 60–90 days
Germination Time:
14–42 days
Notes:
Hemiparasitic; requires host plant roots nearby for successful establishment. Seeds need cold stratification and light for germination.

Pre-treatment: Seeds are treated with 200 ppm gibberellic acid for 24 hrs, then thoroughly rinsed with water. Seeds are then placed into a 90 to 100 day cold, moist stratification at 33.8 to 37.4°F. Some seeds begin to germinate during stratification and are planted as germinants.

Establishment: Seeds are collected in early fall when capsules turn brown and begin to dehisce. The plant prefers to grow in moist areas or meadow regions. There are regional variations in distribution, with the plant found in moist meadows from the prairie to the alpine; from Alaska south to California and New Mexico and east across Canada to Newfoundland. It also inhabits wet meadows, streambanks, and wetlands from mid-montane to alpine elevations.
