This is the flowering perennial Penstemon ‘Red Rocks’. Doesn’t it remind you of a diminutive foxglove? It occupies a part sun nook in our garden beginning it’s blooms in early summer and continuing for weeks. It only grows to a height of about 2 feet and the dainty leaves stay evergreen during our winters. (According to the plant label it’s hardy to zones 4-9.) The little bees just love this plant and it’s fun to watch them busy themselves among the blossoms. I think Penstemon is lovely combined with Campanula and is perfect for a cottage style garden.
