    Polemonium Overview

    A genus of flowering annual or herbaceous perennial plants in the Polemoniaceae family native mainly to parts of the Northern Hemisphere with one member endemic to the Andes. They are found in cool temperate and arctic habitats with many species growing at high altitudes. They are characterised by their pinnately divided leaves that give the genus its common name, Jacob’s ladder. Some species are popular in cultivation for their attractive clustered tubular or bell-shaped flowers and there are many cultivars available.
