--- Penstemon grandiflorus ex. east Minnesota. With way too much rain this spring, I expected stalks to be growing horizontally, but as it seems, it is not an overabundance that does this, rather, it seems to be over fertization.
--- Penstemon hirsutus var. pygmaeus
--- Penstemon cobaea
--- Penstemon cobaea x P. hirsutus var. pygmaeus
--- Penstemon procerus. Grown from seed by fellow Chapter member, this one is very small, but has become one of my favorites.
