Agapanthos grows as an ever expanding clump of evergreen strap shaped leaves around 12in in length. There are up to 18 leaves, arranged in two ranks. The dark blue flowers are trumpet shaped, 1-2in wide, and borne in rounded umbels containing as many as 30 blossoms. These flower clusters are 6-12in across, and held above the leaves on scapes 2-3ft tall. Flowers appear in late summer and are long lasting.
Tolerates neglect, poor soils, and salty coastal conditions. Does best in Full Sun, but can take some afternoon shade. Water regularly, but reduce watering during the winter season. Well established plants are fairly drought tolerant, but may not bloom if not given plenty of water during spring and summer.
Fairly frost tolerant when grown in exposed locations in zone 8, and the roots should be mulched in winter.
These are usually grown in borders or as edging along a driveway or path, but they are also attractive in perennial flower beds. They seem to do well when slightly overcrowded, and therefore do well in pots. These are popular potted plants on poolsides, decks, and porches. The flowers are quite long and great as cut flowers.
