PropagationDescription: Most Ceanothus spp. come well from seed, however with this species, the recovery of the deep lilac color from seed is a longshot. To retain the desired color, propagate with cuttings which usually root well.
Seed Collection: Because dry capsules disperse their seed abruptly with a sudden ejection, it may be necessary to tie cloth bags around the clusters of capsules to catch the seeds.
Commercially Avail: yes
