Agapanthus Black Jack, 7LAs the name suggests, Agapanthus Black Jack is a remarkably dark purple blue African Lily, the buds of which emerge almost black. Hardier than most, this variety fulfils the usual canon of Agapanthus in that its almost architectural flowers, emerging from a mound of richly green, strap like leaves, provide startling colour on lovely arched stems and attract bees. Judged RHS Plant of the Year 2023.
