Agapanthus africanus
Agapanthus africanus (African lily) is a native of the Cape of Good Hope in South Africa. A. africanus is more difficult to grow in gardens than A. praecox, and almost all plants sold as A. africanus are A. praecox.
It has a short stem bearing a tuft of long, narrow, arching leaves 10–35 cm long and 1–2 cm broad, and a central flower stalk 25–60 cm tall, ending in an umbel of 20-30 white, or bright blue, funnel-shaped flowers, each flower 2.5–5 cm diameter.
