Description
This upright penstemon has striking, deep burgundy-purple, to purple and black flowers in several clusters on the upper half of leafy stems, which bear lance shaped leaves, with spoon-shaped basal leaves below. It is a drought-resistant plant coming from Montana, the Rocky Mountains, Arizona and New Mexico.
Sowing Advice
For best results, sow immediately onto a good soil-based compost. Cover the seeds with fine grit or compost to approximately their own depth. They can be sown at any time, and germination can sometimes be quicker if kept at 15 to 20 degrees C. We sow most seeds in an unheated greenhouse and wait for natural germination, as many seeds have built-in dormancy mechanisms, often waiting for natural spring germination, hence giving them a full season of growth.
