Penstemon 'Dark Towers' is from the University of Nebraska that is tough and hardy to zone 3. In midsummer, the plants explode with tall stems of tubular flowers that are deep lavender-rose at the base and lighter pink towards the tips. The deep wine-red foliage is even darker than Penstemon 'Husker Red'.
