Penstemon canescensclick image to enlarge
North Carolina Botanical Garden, Chapel Hill NC.  May 2003. This species native to the SE US states is new to us and quite appealing as an ornamental. The floriferousness combined with the lavender-white corollas is quite amazing even compared to modern hybrids. The big plus for this taxon is that it blooms WEEKS BEFORE the major hybrids and much before 'Husker Red' for example.
