There are many different kinds of agapanthus but the ‘Headborne Hybrids’ are considered the hardiest. They are rhizomatous perennials with fleshy roots and grey-green leathery strap-shaped leaves. Their funnel-shaped flowers are white, or light to deep blue and carried in spheres 3-8″ inches across on thick leafless stems two the three feet high from mid to late summer. Plants bloom best when their roots have become crowded. The flowers are striking in the garden but the foliage is attractive even when the plant is not in bloom. Because the stems tend to lean towards the sun the plants should be located in a south facing border. Agapanthus is very popular with florists as the flowers last a long time in the vase. They look well in large arrangements and may be used effectively as a focal point. In cold climates plants can be raised in pots and brought in doors during the winter.
Cutting: No special treatment
Conditioning: No special treatment but remove flowers from the flowerhead as they fade to keep the head looking fresh. Buds continue to open when the flower stalks are in water.
Preserving: Heads with seed pods can be dried by hanging up-side down in a dry room
