Double-Flowered Camassia

Double-Flowered Camassia

A native to the wet and wild Pacific Northwest United States, camassia quamash is the perfect perennial plant for moist soil sites. Our Double-Flowered Camassia takes adding beauty and texture one step further with its clusters of white double blooms that stud the tall, upright racemes. The moderately tall stems keep the flower clusters visually present in the garden or border. Double-Flowered Camassia appears in late spring to early summer, bridging the gap often left by early bulbs and seasonal perennials. Prefers moist garden sites—ideal for waterside plantings in full sun to partly shaded areas. Great naturalizer! Bulb size: 14+ cm.
