The Guide Lxia Flower


A genus comprising about thirty species of small non-hardy South African bulbous plants. They are not spectacular, but they do possess great elegance and charm, with their small, inch-wide, star-like flowers borne on thin wiry stems. They are much appreciated for cutting and will last long in vases. Above all, they are interesting for their remarkable range of colours, which includes many tints not usually found among other flowers, particularly in the colours such as orange, pink, scarlet, crimson, yellow, and even green and black. They are warm-climate plants, and while the corms may tolerate slight frost they will not survive outside in areas where the ground becomes deeply frozen for long periods. They also make excellent pot plants. The corms are small and should be planted in October–November, mulching the soil surface with a good layer of straw, salt hay, leaves, ashes, or peat if it is likely to freeze during the winter, but removing the protective layer when surface growth appears. Flowering begins about mid-summer and is long-lasting; the small star-like blooms are closely arranged on erect spikes. The foliage is linear, graceful, and grass-like. All the species given here are attractive, especially the so-called green-flowered species, Ixia viridiflora. Corms offered for sale are generally a mixture of hybrid origin, with a very wide selection of colours. Named varieties in separate, distinct colours are, however, also available commercially. Propagation is easily effected by dividing the dormant corms, which should be treated in the same manner as tulips—removed from the soil after flowering, dried, stored, and replanted the following autumn. Ixias can also be raised from seed sown in a warm greenhouse in spring, but several years are necessary to produce flowering-sized corms.
Ixia flexuosa Thunb.
Native to South Africa. Together with Ixia maculata, the most widely grown speciesFlowers pink, in. in diameter, with a darker eye and flattish in form.
Ixia maculata L.
Native to South Africa. Cultivated in European gardens since flowers yellow and orange with a black mark at the throat. Foliage conspicuously ribbed.
Ixia speciosa Andr
Native to South Africa.  Flowers crimson and purple; leaves very thin, narrow, and grass-like.
Ixia viridiflora Lam.
Native to South Africa. Flowers borne in a terminal spike, each bloom about ins, in diameter, star-shaped, and of a remarkable colour best described as electric blue-green with a black centre.
