Cobea Penstemon
There are approximately 280 species of native penstemons in the United States, and many of them grow native in Kansas. This native grows in the eastern 2/3 of the state and can bloom in roadside ditches or along the limestone bluffs of our native prairies. Also known as “beardtongue,” this beautiful plant has white to pale purple flowers that bloom on tall stalks from May through June. Interestingly enough, the flowers will be a different color based on their growing location. They are easy to spot driving down the highway and in native pastures, especially this time of year. Most range in height from 6 to 40” tall, and all attract a wide variety of native bees and pollinators. Several cultivated varieties are available in different bloom colors, heights, and leaf colors. Penstemons grow best in full sun with well-drained soils, as they do not tolerate consistently wet areas in the garden. They can be used in rock gardens or the regular landscape for a spring blooming flower. Penstemons are tolerant of drought and deer and are very low maintenance.
