Polemonium caeruleum ‘White’, also known as Jacob’s Ladder, is a graceful perennial producing clusters of pure white, bell-shaped flowers above fresh green, fern-like foliage. Flowering from late spring into early summer, it brightens shaded areas and adds elegance and texture to mixed borders.
It thrives in moist, well-drained soil and prefers sun or partial shade. For a soft, natural look, plant it with ferns for contrast and Hakonechloa macra for gentle movement and colour that highlights the crisp white blooms.
