PENSTEMON HIRSUTUS 'BLUE FOAM'
In stock
Description
This is a lovely bright form of this species from the mountainous western states of the USA, where it decorates the hillsides with compact clumps of white-throated, pale purple, tubular flowers in spring and early summer.
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.
