Dark Towers Beardtongue is a beautiful flowering plant native to the Western United States and is closely related to foxgloves and snapdragons. This plant is known for its tall spikes of purple-blue flowers that bloom in the late spring and early summer. One of the most striking features of the Dark Towers Beardtongue is its tall, slender spikes of flowers that can grow up to 4 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.
The Dark Towers Beardtongue has a light, pleasant fragrance, often described as sweet and floral. It has an upright, clump-forming growth habit and can reach heights of up to 4 feet. While it is not an evergreen, it does have lush, dark green foliage that remains attractive throughout the growing season. 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 and resistant to deer, making it a good choice for areas with dry conditions or a high deer population.
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 back in the late winter or early spring to encourage new growth.
To propagate the Dark Towers Beardtongue, you can start seeds indoors in the winter or early spring and transplant them outdoors once the weather warms up. You can also 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.
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. Note that the plants can spread through underground runners, so it is a good idea to allow for some extra space between plants to prevent them from spreading too much.
