We modified a Flail-Vac Seed Stripper by mounting heavy loops of chain to the front of the Flail-Vac to provide agitation of the floral canopy to disarticulate seed from the flowers of hoary tansyaster (Machaeranthera canescens (Pursh) A. Gray [Asteraceae]). The modification allowed for multiple, non-damaging harvests that collected only shatter-ready, fully ripe seed. Labor and time associated with post-harvest drying and seed cleaning were reduced because of the decrease in vegetative matter accumulated.
