Germination Information
Pre-treatment: Seeds are sown into trays filled with stabilized medium plugs (Q-plugs). Trays are sealed inside plastic boxes and placed into cold stratification (33.8 to 37.4 °F) for 90 days. Trays are checked weekly and kept moist throughout the stratification period. If mold is evident, trays should be treated with 1% hydrogen peroxide.
Establishment: The plant grows in open grassy hillsides, open woodlands, and coastal grasslands. It is found in CA, OR, and WA with disjunct populations in AL and MO. The seeds are hand collected into a paper bag.
