Team-members who have conducted research on this species: Lee Rodman
All Echinacea are said to be self-incompatible, but experimental evidence of this claim does not yet exist for some Echinacea species. In a breeding systems study in 2011, Lee Rodman found that E. purpurea is in fact self-incompatible, and exhibits style persistence as a sign of pollen limitation.
