8-10" tall by 8-10" wide. Rose Bells Pasque Flower (Pulsatilla vulgaris Rosen Glocke) is native to Europe, and blooms in early to mid-spring with a showy display of large, deep pink flowers. Once the bees have finished pollinating them, these perennial wildflowers cover themselves with feathery seedheads that hold on the plant for many weeks of ornamental interest. Pasque flower is a superb companion plant for spring blooming bulbs like crocus, miniature daffodils, wildflower tulips and other sun loving bulbs.
