Pre-treatment: Seeds are soaked in water for 3 to 4 hours. They are then placed between sheets of blotter paper in nursery flats and wrapped in plastic bags to prevent desiccation. Alternatively, seeds can be directly sown in open flats using a growing medium of 2 parts sand, 1 part mulch and 2 parts perlite.
Establishment: Seeds are hand collected in summer when capsules have matured and begin to split open. Many capsules may contain unfilled seeds. The plant is found in dry washes and canyons; from northern Mexico to southern California east to western Texas and north to southern Utah.
