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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...
