Polemonium caeruleum subsp. caeruleum f. album

Polemonium caeruleum subsp. caeruleum f. album is a refined, cottage-garden perennial, valued for its elegant sprays of pure white, bell-shaped flowers held above finely divided, ladder-like, green foliage in late spring to early summer.

This graceful Jacobs ladder is ideal for borders, wildlife gardens and informal planting schemes, where it brings lightness and charm. Hardy and easy to grow, it’s particularly attractive to bees.

May-August flowering. Grows best in sun or partial shade in moist, well-drained soil. Height & spread: 45cm-60cm x 45cm (18″-24″ x 18″).
