Dark Towers Beardtongue is a beautiful flowering plant developed by Dale Lindgren at the University of Nebraska. The foliage is a deep purple that doesn't fade during summer waves. This plant is known for its tall spikes of pink flowers that bloom in the late spring and early summer. Its slender flower spikes can grow up to 3 feet in height. The flowers are tubular and have five lobes, each containing a pair of small, pointed ears. The plant gets its common name from the long, hairy stamens that protrude from the flowers, resembling a beard.
Dark Towers has an upright, clump-forming growth habit and can reach heights of up to 4 feet. The dense purple foliage stays evergreen in winter. This plant is generally resistant to pests and diseases, making it a low-maintenance choice for gardeners of all abilities. It is also drought tolerant, making it a good choice for areas with dry and hot conditions.
Dark Towers Beardtongue Care
Regarding care, the Dark Towers Beardtongue is relatively easy to grow. It prefers full sun, although it can tolerate partial sun. The Dark Towers Beardtongue prefers well-drained, sandy soil with a pH range of 6.0 to 7.5 but can tolerate various soil types as long as they are well draining. During the establishment phase, water Dark Towers regularly to keep the soil evenly moist but not soggy. Once established, it is drought tolerant and does not require frequent supplemental watering. Feed this perennial in early spring with a single application of a granular, slow-release fertilizer.
Pruning is generally unnecessary, as Dark Towers has a naturally attractive and tidy growth habit. However, if the plant becomes overgrown or leggy, it can be lightly trimmed in mid-summer to encourage a fuller, more compact shape. Remove any tattered foliage in early spring to encourage new growth.
You can propagate the plant by division, which involves dividing the root ball of an established plant and planting the divisions in separate pots or areas of the garden. Pentstemon has dense roots and may require some deep digging to extract them. The best time to divide Dark Towers is late summer or early fall.
Dark Towers Beardtongue Spacing
Space Dark Towers Beardtongue about 2-3 feet apart to allow for proper air circulation and room for the plants to grow. This will help to prevent overcrowding and promote healthy growth. You can also grow it in a container with a diameter of a least 16 inches.
