Large 6" to 24" panicles of showy, plume-like clusters of small, creamy-white flowers that rise above the foliage from May to June. The flowers have five oval-shaped petals. Grows best in moist, rich soil in partial shade, although it will do fine in full sun if given consistent moisture. Amend the soil with generous amounts of organic matter before planting. Space plants 2-4 feet apart, providing plenty of room to accommodate their mature size. Once established, transplanting this species is a very difficult task. They tend to grow slowly the first few seasons. The wide-open spaces between young plants can be filled with annuals until the goatsbeard reaches its mature size.
