Family Scientific Name: Fabaceae
Family Common Name: Pea Family
Scientific Name: Lupinus latifolius
Common Name: broadleaf lupine
Species Code: LULA4
Propagation Goal: seeds
Propagation Method: seed
ProductType: Propagules (seeds, cuttings, poles, etc.)
Time To Grow: 0
Pre-Planting Treatments: Seed has a hard seed coat that must be scarified with hot water or a seed tumbler. The following scarification technique was successful at Horning Seed Orchard: Put seed in nylon or cotton bag(s). Boil water in a container large enough to fit the bag(s). Remove container from heat and immerse bag(s) in water for one minute. Remove seed from water and rinse immediately with cold water. Drip dry and sow promptly. If seed is not completely dry before sowing, talc powder can be sprinkled on seed for easier handling. Ohter sources recommend letting seed remain in water as it cools, but that technique produced almost no germination at Horning Seed Orchard.
