A charming collection of Jacob’s Ladder perennials, valued for their elegant fern-like foliage, colourful spring-to-summer flowers and compact, easy-care growth habit, perfect for cottage gardens, woodland borders and pollinator-friendly planting schemes.

Polemonium varieties are treasured for their finely divided, ladder-like foliage and clusters of delicate bell-shaped blooms held above attractive leafy mounds. Depending on the variety, flowers appear in shades of blue, violet, lavender or purple, while several cultivars also offer striking golden or variegated foliage that provides season-long interest. Blooming from late spring into summer, these compact perennials typically reach 30–60 cm tall and wide, making them ideal for front-of-border displays, shaded garden beds, containers and wildlife-friendly gardens.

Our Polemonium plants are professionally grown in high-quality peat-free compost and freshly delivered directly from our UK nursery in Yorkshire, in plastic-free, giftable packaging. Supplied as large, garden-ready plants in generous 3-litre pots, they feature strong, well-developed root systems that establish quickly and return year after year with increasingly impressive floral displays.
