Propagation Notes Eryngium yuccifolium
Seed Collection - Late in the fall, once flowers heads are brown and dry. Loosen seeds from seed head; dry for a few weeks.
Stratify - Cold/moist stratify for 60 days. Store seeds in a small plastic baggie that contains a sufficient amount of vermiculite to cover the seed. Germination Rates - Highly successful! Germination rate is especially high when starting seeds indoors Fall Sowing - We have had very good success sowing Rattlesnake Master seed outdoors in the fall. Protecting flats with a small cold frame prevents heavy spring rains from damaging tender seedling and serves as a barrier to small mammals and rodents during the winter
