In stock
Description
Another of the easier, drought tolerant penstemons, this one forms a lowish mat of leathery dark-green leaves, with upright stems bearing tubular, pure white flowers. It make a very showy early summer display in the rock garden, foliage turning an attractive bronze-red colour in winter.
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.
