Propagation of endangered species: Variable germination of pink sandverbena from Pacific coast beaches

Pink sandverbena (Abronia umbellata ssp. breviflora) is an endangered plant of Pacific Coast beaches. Restoration efforts have focused on the development of seed germination and field propagation techniques. Germination in the laboratory was highest when seeds were removed from the fruit and received alternating temperatures (20 C/30 C) and photoperiods. Benefits from cold stratification differed strongly from site to site and year to year. Field-sowing of seeds is also a viable propagation method.
