Based on an September 2020 extract of the California Plant Rescue Database, California Botanic Garden holds 7 accessions of Deinandra minthornii in orthodox seed collection. There are as many as 15763 seeds of this species in their collection - although some may have been used for curation testing or sent to back up.
Based on an August 2020 extract of the California Plant Rescue Database, California Botanic Garden has collected 4 seed accessions of Deinandra minthornii from 4 plant occurrences listed in the California Natural Diversity Database. These collections together emcompass 102 maternal plants
Endemic to California, Hemizonia minthornii occurs in Los Angeles and Ventura Counties. Threats include development.
Threats include residential development, new roads and road maintenance.
There were over 20 known occurrences of Santa Susana tarplant, but one-fourth of these have not been seen in many years and their current status is unknown.
Remaining habitat is spread among several private landowners and the Los Angeles Department of Water and Powers, therefore little of this plant's habitat is protected.
A habitat conservation plan is needed and research on its reproductive biology, germination and growth and habitat requirements will be necessary in formulating a conservation strategy.
