Pre-treatment: None required. However, seed lots have been observed to germinate at higher rates after storage in cold, dry conditions.
Establishment: Wild seeds are collected when the capsules begin to split. Plants in seed increase plantings are cut and dried in paper bags at room temperature. The plant flowers and matures seed indeterminately, thus a judgement must be made as to when to cut the plants to maximize seed production. Seeds are small and dark brown in color. General Distribution: Northwestern US east to South Dakota. Usually found on south slopes in dry, open grassland and open Ponderosa pine forest.
