One single plant of Polemonium ( Jacob's Ladder) survived last harsh winter in my garden. Obviously, ordering new plants will be one of the autumn garden tasks.
I love this plant because of the heavenly blue colour of it's flowers. The foliage is also very interesting being purplish-black in colour. This plant is easy to grow providing a sunny spot and average moisture. No special preferences for the soil type. The plant is supposed to be self-seeding so, I am expecting some seedlings too.
