Based on an September 2020 extract of the California Plant Rescue Database, California Botanic Garden holds 15 accessions of Blennosperma bakeri in orthodox seed collection. There are as many as 11532 seeds of this species in their collection - although some may have been used for curation testing or sent to back up.
Endemic to California, Blennosperma bakeri is known from fifteen occurrences, six of which may be extirpated or very degraded.
