Polemonium caeruleum
Polemonium caeruleum is a charming native perennial valued for both its delicate flowers and attractive feathery foliage. Neat clumps of ladder-like leaves give the plant its common name, while upright stems carry clusters of soft blue flowers with prominent yellow centres in early summer.
Ideal for cottage gardens, wildlife borders and naturalistic planting schemes, this easy-going perennial grows well in sun or partial shade in fertile, moist but well-drained soil. The nectar-rich blooms are particularly attractive to bees and other pollinating insects. :contentReference[oaicite:0]{index=0}
