'Plant of the Week' for the last week of April. This beautiful garden Perennial is known as the Pasque Flower (Easter Flower) due to its timing of bloom. Pulsatilla Vulgaris is one of the nicest early bloomers. It is a plant that can naturalize and live quite comfortably without much care. It can live in poor soils and has few pests. This plant and some similar varieties are also known as Prairie Crocus.
