Family Scientific Name: Liliaceae
Family Common Name: lilly
Scientific Name: Camassia leichtlinii
Common Name: Camas
Species Code: CALES
Ecotype: willamette valley, oregon
General Distribution: moist meadows of the western US, from California to Washington, Nevada, Idaho, and Montana
Propagation Goal: bulbs
Propagation Method: seed
ProductType: Container (plug)
Stock Type: bulbs
Time To Grow: Weeks
Target Specifications: 2 year old bulbs
Propagule Collection: Easy. Cut off the entire flower stalk in late spring or early summer (late June to mid-July) after the seeds turn black and most of the pods (capsules) change from green to tan but are not yet open. As capsules mature on the plant, they split open at the top to reveal the seed but remain upright. Place the stalks, capsules, and any loose seed in paper bags and keep in a warm place until dry. Threshing is unnecessary since all the pods dehisce as they dehydrate. The seed will drop to the bottom of the bag after shaking. Seeds per pound: 70,000-90,000
Propagule Processing: Usually an air-screen machine is sufficient to remove chaff, weed seeds, and empty or immature seeds.
Pre-Planting Treatments: Camassia leichtlinii germinates from seed best when exposed to 90 days of c/m (38F) stratification. Highest germination occurs when seeds are exposed to temperatures of 50-55 degrees following stratification.
