Penstemon, also known as the beardtongues, is a large genus of approximately 280 flowering plant species. These plants are mostly native to the Nearctic region, with a few species found in the North American part of the Neotropics. It is the largest genus of flowering plants endemic to North America. The scientific name, penstemon, is commonly used as a common name for all Penstemon species, alongside beardtongues.
Previously classified in the family Scrophulariaceae, recent genetic research has placed Penstemon in the expanded family Plantaginaceae. The exact number of species is uncertain due to ongoing research, which aims to determine if some named species are actually subspecies or misidentifications of already identified species.
One specific species, Penstemon digitalis, is a flowering plant in the plantain family. It is native to eastern Canada and the eastern and southeastern United States. This species produces white flowers during the summer. Another noteworthy variety is 'Blackbeard', which is an upright and compact selection of beardtongue. It features dark purple foliage and pink flowers held on sturdy, dark purple stems. These blooms are highly attractive to hummingbirds and other pollinators. Mature 'Blackbeard' plants can reach up to 3 feet in height with a 2-foot spread. This variety was chosen as a seedling of Penstemon digitalis 'Pocahontas'.
In summary, Penstemon is a diverse genus of flowering plants, mainly found in North America. It is now classified under the family Plantaginaceae. One notable species, Penstemon digitalis, is native to eastern Canada and the eastern and southeastern United States. Additionally, the 'Blackbeard' variety stands out with its dark purple foliage and attractive pink flowers, which are highly appealing to pollinators.

How to care for Beardtongue
Caring for Beardtongue is a breeze, as it is highly adaptable and forgiving to minor neglect.
Beardtongue requires abundant, bright, and direct light to thrive. The best placement for this plant is within one foot of a window to ensure it receives enough light. If you live in an area with more extreme weather, such as hot summers or cold winters, you may need to adjust the placement of the plant accordingly. During hot summer months, it is important to place the plant away from full sun, as this can cause the leaves to yellow or burn. During cold winter months, it is best to move the plant closer to the window to take advantage of the extra light that can help it survive. By keeping an eye on the current weather in your area, you can make sure your Blackbeard Beardtongue is always in the right place to thrive.
During the cold period, it is common for Beardtongue to go dormant, resulting in a slowdown of growth. To accommodate this, waterings should be spaced out more.
