Polemonium caeruleum subsp. himalayanum CC7325
25 seeds per packet.
Seeds have been collected from our plants which were grown from seed collected by Chris Chadwell on his expedition to the Himalayas in 2013. Attractive, blue flowers are produced from June to September on tall stems. Height to 1 metre. Moist, well-drained soil in sun to semi-shade. Plants can flower one year from sowing.
Sow from March to June. Cover seed thinly, press in gently and keep top of compost from drying out. Keep pot warm at 15 to 20°C until germination, then move to somewhere cooler.
Carefully prick out seedlings when they have developed true leaves and are large enough to transplant to individual pots to grow on.
