Polemonium caeruleum ssp. himalayanum
A few plants available of this seed-grown variety. Lovely, leafy plants with finely-divided green foliage. Tall stems should bear gorgeous deep blue flowers, a little larger than the typical Jacob’s Ladder. Plants will reach up to a metre when in flower and will do best in a moisture-retentive, rich soil in a partly shaded position. 9cm pot.
