Fleshy rooted evergreen with relatively short, strap-like leathery leaves and strong stems supporting the large umbels of tubular blue flowers.
Not very hardy in Britain, but will tolerate several degrees of frost if located in a favourable, well drained, position. Must have good sunlight to flower successfully. Prefers a light, slightly acid, very well drained soil.
By division, which is best done only when clumps get very congested.
From seed, sown as soon as ripe or in spring. Best left undisturbed in their first year. May take 2 or 3 years to produce flower.
Often confused with Agapanthus praecox.
