We received seed of this plant from American nursery Alplains. It was collected in Mineral County, Colorado. The stock plants grow in an altitude of more than 3300 m and Alplains claims that it is the darkest flowered population that have ever seen.

It is a plant that can be found throughout the southwest of the USA. It isn`t restricted to extrem dry soil like other Penstemons of that region, but does well in the garden in ordinary soils. However it is at its best in the rockery, where it is very good plant for the background.
