Do you need to stratify or scarify an Indian Blanket or Scarlet Bugler Penstemon?
There are several Indian Blanket species. Gaillardia X grandiflora, Gaillardia aristata, and Gaillardia pulchella come readily to my mind. Gaillardia X grandiflora is a hibrid of G. arisata and G. pulchella. None of these need special treatment to get the seeds to sprout. In zone 8 we sow G. pulchella in October, and it sprouts readily. It hugs the ground over the winter, growing rapidly when the weather begins to warm in the spring.





Because common names are often applied to different species of the same genus, or even to plants of a completely different genus, it is important to use the scientific name when seeking specific growing information.





Penstemon centranthifolius "Scarlet Bugler" is listed as needing stratification, i.e. cold moist storage followed by a warm planting bed. This is usually accomplished by sowing the seeds outdoors in the fall, and allowing the winter cold to provide natural stratification.
