Here I am offering a Pint Plant of Polemonium yezoense Purple Rain or purple Jacobs ladder. An unusual form of Jacobs Ladder, this plant forms a full mound of ferny foliage in a striking black purple shade, later becoming green. Upright stems of soft blue phlox like flowers appear in late spring. An unusual plant for the woodland garden or edging in the border. Nice as a cut flower. Evergreen in mild winter areas. Growing 1 to 2 feet and is hardy in zones 4a to 8b.
