Penstemon in Alabama
When I was living in the New Mexico Rockies, I became very fond of the red penstemons that were common there - even growing on the roadsides in town!! The ones we have here are not as spectacular, being pale to medium purple, but are still very nice to have. I have been growing them for a year now. Last year I had single plants of P. calycosus and P. tenuis; this year they have formed clumps, especially calycosus, and are in bloom right now. P. 'Husker Red', whose foliage is burgundy but whose flowers are pale purple, survive the winter and also has started to clump but seems to bloom later. I've not seen hummers around them yet, but they are obviously well suited to be hummer plants.
