Pre-treatment: Heat fresh water to 190F. Remove container from heat. Add seeds, cover, and let soak for 12 hours.

Establishment: Seeds are collected between May 1st and August 1st. Mature inflorescences are brown, papery pods. Each pod contains 1 seed. L. scoparius is found on dry slopes and fans below 5,000 feet elevation; from Humboldt and Plumas counties to Lower California.
