Freesia laxa, commonly known as flowering grass, [2] is a small species of cormous flowering plant in the family Iridaceae, from eastern and southern Africa, from Kenya to northeastern South Africa. [1] It is grown in gardens as an ornamental plant.

Description

Freesia laxa grows from corms, reaching about 15–30 cm (6–12 in) tall. The green leaves are arranged in a flat "fan" from which the flower stalk emerges. The flowers are flattened, about 2 cm (0.8 in) across. Their colour varies considerably. The ground colour is red, white or pale blue. The bases of the lowest three tepals usually have a darker marking, which may be red or purple, although it is absent in the pure white form. The seeds are bright red. [3] [4]

It is native to the eastern side of southern Africa, [3] from Kenya to South Africa, [1] where it grows in somewhat moist conditions. It dies down to a corm in the winter, growing again at the end of spring and flowering in summer. [3] In the wild, in the Southern Hemisphere, it flowers between October and December. [4]

Systematics

This small bulbous species has been known by a variety of names. The name Gladiolus laxus was originally published by Carl Thunberg in 1823. Peter Goldblatt transferred the species to Anomatheca laxa in 1971; Nicholas Brown changed it to Lapeirousia laxa in 1928; Goldblatt with his colleague John Charles Manning settled on Freesia laxa in 1995. [1] Separately, in 1830, John Lindley described Anomatheca cruenta which John Baker transferred to Lapeirousia cruenta in 1892. [5] Lindley's plant is now regarded as part of Freesia laxa. [1]

Forms with blue flowers are treated as Freesia laxa subsp. azurea, other forms being placed in Freesia laxa subsp. laxa. [6]

Cultivation

Freesia laxa is sufficiently hardy to be grown outdoors in all but the coldest parts of the British Isles. [3] It requires a light soil and a sunny position. In colder areas, the corms can be lifted and dried off during the winter. It can be propagated by dividing groups of corms or by seed. [3] It can be somewhat invasive through self-sowing when grown in favourable conditions. [6]

This plant [2] and the white-flowered cultivar F. laxa var. alba [7] have gained the Royal Horticultural Society's Award of Garden Merit. [8]

<i>Crocus</i> Genus of flowering plants in the family Iridaceae

Crocus is a genus of seasonal flowering plants in the family Iridaceae comprising about 100 species of perennials growing from corms. They are low growing plants, whose flower stems remain underground, that bear relatively large white, yellow, orange or purple flowers and then become dormant after flowering. Many are cultivated for their flowers, appearing in autumn, winter, or spring. The flowers close at night and in overcast weather conditions. The crocus has been known throughout recorded history, mainly as the source of saffron. Saffron is obtained from the dried stigma of Crocus sativus, an autumn-blooming species. It is valued as a spice and dyestuff, and is one of the most expensive spices in the world. Iran is the center of saffron production. Crocuses are native to woodland, scrub, and meadows from sea level to alpine tundra from the Mediterranean, through North Africa, central and southern Europe, the islands of the Aegean, the Middle East and across Central Asia to Xinjiang in western China. Crocuses may be propagated from seed or from daughter cormels formed on the corm, that eventually produce mature plants. They arrived in Europe from Turkey in the 16th century and became valued as an ornamental flowering plant.

Freesia is a genus of herbaceous perennial flowering plants in the family Iridaceae, first described as a genus in 1866 by Christian Friedrich Ecklon (1886) and named after the German botanist and medical practitioner, Friedrich Freese (1795-1876). It is native to the eastern side of southern Africa, from Kenya south to South Africa, most species being found in Cape Provinces. Species of the former genus Anomatheca are now included in Freesia. The plants commonly known as "freesias", with fragrant funnel-shaped flowers, are cultivated hybrids of a number of Freesia species. Some other species are also grown as ornamental plants.
