Polemonium
''Polemonium'', commonly called Jacob's ladders or Jacob's-ladders (the name derived from the Biblical story), is a genus of between 25 and 40 species of flowering plants in the family Polemoniaceae, native to cool temperate to arctic regions of the Northern Hemisphere. One species also occurs in the southern Andes in South America. Many of the species grow at high altitudes, in mountainous areas. Most of the uncertainty in the number of species relates to those in Eurasia, many of which have been synonymized with '' Polemonium caeruleum''. ''Polemonium'' are perennial plants (rarely annual plants) growing 10–120 cm tall with bright green leaves divided into lance-shaped leaflets. They produce blue (rarely white or pink) flowers in the spring and summer. Some species are used as food plants by the larvae of some Lepidoptera species including '' Coleophora polemoniella''. Species Kew's Plants of the World Online accepts 37 species. Many are locally known sim ...

Polemonium Reptans
''Polemonium reptans'' is a perennial herbaceous plant native to eastern North America. Common names include spreading Jacob's ladder, creeping Jacob's ladder, false Jacob's ladder, abscess root, American Greek valerian, blue bells, stairway to heaven, and sweatroot. Description Jacob's ladder grows tall, with pinnate leaves up to long with 5–13 leaflets. The leaves and flower stems grow from a vertical crown with abundant fibrous roots. The flowers are produced in panicles on weak stems from mid to late spring. They are 1.3 cm ( in) long and have five light blue-violet petals that are fused at the base, enclosed by a tubular calyx with five pointed lobes. The pollen is white. The stigma extends beyond the anthers, making self-pollination difficult, so insects must cross-pollinate for the plants to produce seed. Pollinated flowers develop into an oval pod with three chambers, 6 mm ( in) long, which is enclosed by the green calyx. The plant spreads by reseeding ...

Polemonium Caeruleum
''Polemonium caeruleum'', known as Jacob's-ladder or Greek valerian, is a hardy perennial flowering plant. The plant produces cup-shaped, blue or white flowers. It is native to temperate regions of Europe. Growth The plant usually reaches tall and broad, but some occasionally grow taller than . It can grow in North American hardiness zone 2. Habitat The plant is native to damp grasslands, woodlands, meadows and rocky areas in temperate areas of Europe and Asia. Cultivation The plant normally prefers soil that is rich in moisture and lime with partial shade. Normally hardy, some cultivars (e.g. 'Blue Pearl') behave as tender biennials, which means they are effectively annuals in cooler climates (below hardiness zone 6). The plant is known to have a few landscape uses as well such as attracting beneficial insects. The plant itself is convenient for container planting due to the shape of its growth. The flower may be presented as a cut flower or foliage and may be added to bou ...

Polemonium Boreale
''Polemonium boreale'', the northern Jacob's-ladder or boreal Jacobs-ladder, is a plant native to the most of the high arctic. In Greenland it is found only in a small area on the east coast. It is not very common. The whole plant is pubescent, with long woolly hairs, glandular, and grows to 5–10 cm tall. The basal leaves are more or less alternate, and pinnate, with numerous leaflets. The flowers are produced in a more or less capitate inflorescence, each flower bell-shaped, blue, 15 mm long, 2.5 times longer than the calyx. The plant has a very unpleasant smell, and grows on gravelly slopes and in crevices.
