Beardtongue | Known for their early summer flowers Penstemons are often times overlooked for their evergreen foliage! Planted in mass, these plants add a tremendous amount of interest to the winter landscape. Add a layer of snow to the ground and the foliage stands out even more so! 'Blackbeard' will grow up to about 30" in late spring and be covered in pink flowers in early to mid summer. Great sun perennial for foliage, bloom and pollinators.
