Spikes of bright blue funnel-shaped flowers, dramatically flared at the end, open in whorls along stems covered in ash-colored hairs. This drought-resistant plant grows in open sagebrush scrub, juniper woodlands and rocky ridges, into very high elevations in the wild.
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.
