Jacob's Ladder Plug Plants Polemonium caeruleum
Common names include ladder-to-heaven and charity.
A graceful perennial wildflower with ladder-like pinnate leaves and clusters of bell-shaped blue-violet flowers from June to August. Jacob’s ladder is a magnet for pollinators, especially bees and hoverflies, and adds a touch of cottage-garden charm to borders, meadows, and wildlife planting schemes.
Thriving in moist, well-drained soils in sun or partial shade, it’s ideal for woodland edges, damp meadows, and naturalistic planting. Historically valued as a medicinal and ornamental plant, Jacob’s ladder brings beauty and biodiversity to any setting.
Our strong, healthy plug plants are grown in 40cc cell trays and ready for planting straight into their final position.
Sourced from UK-grown native stock, these plugs are perfect for introducing this traditional wildflower where seed germination may be unpredictable.
We recommend planting 5–7 plugs per square metre for the best effect.
