Lauritzen Gardens established a conservation seed bank for Eriogonum helichrysoides in 2019 from collections made on the Smoky Valley Preserve of The Nature Conservancy in Logan County, Kansas.  The population appeared to be stable and the associated rock outcrop plant community in good ecological condition.  Collections were made from 50 material lines.  An estimated 4,000 seeds were collected.  The seed of this wild buckwheat species was not difficult to collect but processing proved challenging since the individual achenes are very small (3 mm long).  Seed viability tests for these accessions will be conducted in early 2020, as well as germination tests.
