Developed by Dale Lindgren at the University of Nebraska, ‘Dark Towers’ has super-dark maroon-purple foliage that adds depth and contrast to the landscape. Slightly taller than ‘Husker Red’, ‘Dark Towers’ displays a commanding presence and during early summer explodes into bloom with masses of tubular hummingbird attracting flowers of deep lavender-rose and light pink. ‘Dark Towers’ is also outstanding for its tolerance to heat and humidity. It is long-lasting, thrives in various soil types, and is great for the back of a mixed bed or border, naturalize, as a specimen, or in combination with numerous companions.

Care
Watering:
'Dark Towers' Beard Tongue is moderately drought tolerant but benefits from occasional watering, to maintain soil in a moist but not wet condition, during the summer months.
Fertilizing:
'Dark Towers' Beard Tongue is a moderate feeder, benefiting from a couple of annual applications of slow release fertilizer. A spring application of a 3-1-2 ratio (such as a 15-5-10) can be applied at a rate of about 10 pounds per 1000 square feet, and during early fall, an application of a 2-1-2 ratio (such as a 10-5-10) can be applied to encourage root development and cold hardiness.
Pruning:
'Dark Towers' Beard Tongue should be enjoyed all winter long, then, during early April before it begins to grow again, it should be pruned or mowed back to ground level.
