Germination Information
Pre-treatment: None required
Establishment: Seeds from wild-collected seed from Garfield County, Colorado had relatively low germination regardless of the imposition of 12 weeks of winter conditions. This suggests that seeds in this species may have different dormancy-break requirements, and seeding timing may not significantly influence germination of sown seed. Additional research is needed to confirm the specific length of conditions needed to break dormancy and allow germination in the maximum number of seeds. Additional research is also needed to determine the extent to which these results are characteristic of the species.
