POLEMONIUM CAERULEUM 'CASHMERIANUM'
$3.97 / packet
In stock
Description
Predictably from Kashmir comes this bushy form of "Jacob's ladder" with ferny foliage and solid clusters of large silky pale blue flowers in early summer. One of the best butterfly plants you can grow, it prefers fertile, well-drained soil which is not parched, in sun or semi-shade.
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.
