Vasek's clarkia Profile Vasek's clarkia Clarkia tembloriensis ssp. Each capsular fruit contains many seeds. The seeds of this annual plant germinate in response to winter rains.
Some seeds probably persist ungerminated for many years, as occurs in closely related species.
Vasek's clarkia flowers in April and is self-pollinating. This taxon is endemic to the Caliente Hills of Kern County, which are southeast of Bakersfield. At one time, three separate colonies were known within the area of endemism, but only two remain. The reasons for the disappearance of the other colony are unknown. The other is Temblor clarkia, Clarkia tembloriensis ssp.
