Perennials

POLEMONIUM

Lush rosettes of finely divided, ferny, light to medium green foliage. Blossom stalks are typically leafy and bear clusters of bell-shaped flowers in spring or early summer. Good under trees. Grow from seed or from divisions made after bloom or in spring; give well-drained soil. Many species are choice wildflowers from Western mountains.

Polemonium caeruleum

Native to Europe and Asia. Fairly upright-growing plant to 1–3 ft. tall and 1–1 1/2 ft. wide. Lavender-blue, pendulous, 1-in. flowers. ‘Brise d’Anjou’, with each leaflet neatly outlined in white, is one of the most striking of variegated-foliage plants.
