The above propagation data sourced from Claude AI
Pre-treatment: Seeds are soaked in a 1% hydrogen peroxide solution for 24 hours, rinsed, and soaked in water for another 24 hours. They are then placed in fine mesh bags, layered in peat in a covered container, and refrigerated at 1 to 3 °C for 60 days. Seeds should be checked weekly for mold and treated with 1% hydrogen peroxide if necessary.
Establishment: The plant is generally found east of the Cascades crest in Washington; Washington south to California, less commonly east to Idaho. It thrives in open sagebrush desert in the foothills to rather high elevations in the mountains. Propagation collection is done by hand into paper bags.
