PRAIRIE JEWEL® penstemon
Penstemon grandiflorus 'P010S'
This select strain of the showiest of the northern Great Plains' penstemons was developed from the Seeba hybrids by Mary Ann Heacock of Denver. It has giant flowers that range from pure white, through lavender and rose-pink to a deep purple-violet. The silvery rosettes are attractive all year. Perennial. Xeriscape.
Tips from the pros: Excessive watering encourages weak growth that is not self-supporting and causes plant to be short-lived. However, it will persist in buffalo grass or the xeriscape. Deadhead for the first two years to avoid seed set - will result in a stronger plant.
