Jacob's Ladder (Polemonium)

Jacob’s ladder is a common name used for members of the genus Polemonium, a group of herbaceous perennials with finely divided foliage and clusters of bell-shaped flowers. Species and cultivars vary in flower color, flowering season, moisture needs, and mature size, so this genus-level entry serves as a broad garden reference rather than a single selection profile. [Missouri Botanical Garden](https://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?isprofile=0&taxonid=261656) describes Polemonium as a genus of about 25 perennial species across Europe, Asia, and the Americas; [NC State Extension](https://plants.ces.ncsu.edu/plants/polemonium-reptans/common-name/jacobs-ladder/) provides an example of a species called Jacob’s ladder. ## Garden Use Use species-specific profiles to choose a site and confirm mature size, bloom period, and moisture preferences. Existing dimensions and season values are retained for this broad entry and should not be taken as universal across the genus. ## Maintenance Follow the needs of the selected species or cultivar. In general, maintain even moisture during establishment and remove spent or damaged growth as appropriate.
