Exposure: part shade-sun Soil: Medium Height: 1-1.5 feet Bloom: May
Description: Very attractive blue/purple blooms for partial sun-shade gardens. Even after blooms have faded, the foliage maintains a nice mounded shape. Will spread, but not aggressively. A TLC garden favorite.
Attracts: The nectar and pollen of the flowers attract bees primarily, including honeybees, bumblebees, little carpenter bees (Ceratina spp.), mason bees (Osmia spp.), cuckoo bees (Nomada spp.), Halictid bees (Augochlorella spp., Lasioglossum spp.), and Andrenid bees (Andrena spp.). A species from this last group, Andrena polemonii, is a specialist pollinator (oligolege) of Polemonium spp. (Jacob's Ladder, Greek Valerian). The flowers are also visited by Bombylius major (Giant Bee Fly), butterflies, skippers, and moths, which seek nectar. The larvae of two moths, Coleophora polemoniella and Scrobipalpula polemoniella, mine the leaflets.
