I grew this species from seed 3 years ago. It bloomed in the second year. The plant habit is similar to the common P. fruticosus but the leaves of the variety scoulei are much narrower. The flowers of 'Albus' are pure white, a relatively rare colour in penstemons. This plant has done well in my rock garden under full sun and slightly acid conditions.
