Polemonium caeruleum is a dainty perennial that will readily seed about between other plants creating a naturalistic, cottage-garden look. From clumps of sparse foliage arise tall, upright stalks topped with clusters of nodding, blue flowers with golden stamens. Flowering May to June, it makes a charming addition to early summer borders in part shade, woodland gardens or beneath deciduous trees and shrubs. It is perfect for wildlife-friendly gardens as the flowers are a valuable source of early nectar and pollen for insects emerging from hibernation. The pretty foliage of Polemonium caeruleum is an attractive feature in itself, forming little leaflets arranged into a ladder pattern which has earned it the name of ‘Jacobs Ladder’. Height: 80cm (31in). Spread: 30cm (12in).
Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.

Thompson & Morgan strives to ensure that all its plants are delivered to you in the perfect condition for planting. While the majority of our nursery plants cope well with slight delays in intransit, sadly, the time it takes to deliver to certain locations in the UK means that we can't guarantee this for some of our smaller plug products and tender bedding and vegetable lines, which do not respond well to the extra journey time. So regretfully while we offer the majority of our live plant offering nationwide, we are unable to ship plugs, begging plants and tender vegetable plants to the following areas: HS, IV41-IV49, IV51, IV55-56, KW15-KW17, PA34, PA41-48, PA60-PA78, PA80, PH40-PH44, TR21-TR24, ZE1-ZE3
