This is an amazing selection of Penstemon. Deep purple evergreen foliage shoots up in spring and is covered in clear white flowers. The flowers and foliage color contrast puts on an amazing show! Great sun perennial for foliage, blooms, and pollinators. Planted in mass, it makes the obvious impact in the spring, but during the winter, the carpet of purple foliage can really help beat the winter blues! Photo courtesy of Walters Gardens.
