Dark Towers Penstemon (Penstemon 'Dark Towers') Pollination Info

Dark Towers Penstemon is a perennial plant that belongs to the family, Plantaginaceae. It is a hybrid penstemon that was developed in the early 2000s by crossing Penstemon digitalis (foxglove beardtongue) and Penstemon 'Husker Red' (a cultivar of Penstemon digitalis).

The flowers of Dark Towers Penstemon are tubular in shape, with two lips and five lobes. They are about 1 inch long and come in shades of deep burgundy-red. The flowers bloom from late spring to early summer, and their nectar and pollen attract various pollinators, including bees, butterflies, and hummingbirds.

Dark Towers Penstemon is an excellent plant for pollinators, as it produces abundant nectar and pollen-rich flowers. The bees and butterflies brush against the anthers, where they collect pollen, which is then transferred to the stigma of other flowers, promoting pollination. Hummingbirds, on the other hand, feed on the nectar and inadvertently pick up pollen on their feathers, which is then deposited on the stigma of other flowers they visit.

Dark Towers Penstemon is a self-fertile plant, meaning that it can pollinate itself and produce viable seeds. However, cross-pollination by insects and other animals can promote genetic diversity and increase the chances of survival for the species.

To attract pollinators to your Dark Towers Penstemon, plant it in a sunny location with well-draining soil. Water it regularly and fertilize it with a balanced fertilizer once a month during the growing season. Deadhead spent flowers to promote continuous blooming and ensure that the plant remains healthy and attractive to pollinators.
