Monkshood is a perennial that blooms in late summer to early fall. It likes part shade and moist soil. At 3-5 feet high in bloom, it is a middle to back of the border plant in most gardens. It is slow to establish or re-establish when moved.
Each fall I enjoy watching the buds form and open when most of my perennials have stopped blooming or are in seasonal decline.
All parts are posionous so it’s not suitable for gardens where children and pets are likely to go. Gloves are recommended when handling this plant.
