Agapanthus 'Queen Mum'

A tall, bicolored agapanthus that carries large rounded flower heads of white petals flushed blue at the base. Stems rise well above the foliage in mid to late summer, giving a bold architectural look in borders and large containers. Plants prefer full sun and moist but well‑drained soil, and benefit from winter mulch where freezes occur. In much of North America it is treated as a perennial in warm coastal and southern regions and as a container plant elsewhere. All parts are harmful if eaten; wear gloves if the sap contacts skin.
