Polemonium yezoense 'Purple Rain Strain' (Jacob's Ladder)

Polemonium yezoense 'Purple Rain Strain,' commonly known as Jacob's Ladder, is a clump-forming perennial admired for its lacy, fern-like foliage that emerges deep purple and matures to bronze-green. In spring to early summer, it produces clusters of bell-shaped, violet-blue flowers on upright stems, adding delicate charm to shaded or partially sunny garden areas. The combination of colorful foliage and vibrant flowers makes it a standout in borders, woodland gardens, or shaded perennial beds.

Polemonium yezoense 'Purple Rain Strain' prefers rich, well-drained soils with consistent moisture, making it an excellent choice for damp or shaded garden areas. It attracts pollinators such as bees and butterflies and is deer-resistant, making it a low-maintenance addition to wildlife-friendly gardens. Deadheading spent flowers can encourage fresh foliage growth and prolong its attractive appearance. This variety pairs beautifully with other shade-loving perennials like hostas, astilbes, and ferns for a lush, layered garden display. Regular watering during dry spells ensures optimal health and vibrancy.
