We have developed seed increase protocols for Region 2 US Forest Service Sensitive Species Ipomopsis aggregata (Pursh) V.E. Grant ssp. weberi V.E. Grant & Wilken (rabbit ears gilia [Polemoniaceae]) and hemiparasitic Castilleja flava S. Watson var. flava (yellow Indian paintbrush [Orobanchaceae]). Both species exhibit life history traits such as biennial habit, obligate outcrossing pollination strategy, and indeterminate capsule ripening or hemiparasitism, requiring development of efficient and less expensive seed increase methods.Robertson N, Rhoades EO. 2023.
