Read about Sparaxis in the Standard Cyclopedia of Horticulture

Sparaxis (Greek word referring to the torn or lacerated spathes, a character which distinguishes this genus from Tritonia). Iridaceae. Wand-flower. Bulbs or corms with fibrous coating, the plants suitable for outdoor planting but grown mostly under glass. Stems simple or slightly branched: lvs. few, flat, sword-like or broadly linear, erect or falcate: spathes few, remote or sometimes solitary, broad-striate or frequently marked with short brown lines: fls. 1 to a spathe, sessile, rather large, yellow; perianth-tube short and slender, 6-lobed; ovary 3-celled: caps. membranaceous, ovoid or oblong, included in the spathe.—About 3 species, Cape Colony, S. Afr. Sparaxis is a group of spring-blooming Cape bulbs of the Ixia tribe, with spikes of 6-petaled, more or less funnel-shaped fls. 1-2 in. across and exhibiting an extraordinary range of color and throat - markings. These plants are less popular than ixias, which they much resemble. The plants are dwarfer and more compact than ixias, usually 6-12 in. high, the spikes are shorter and fewer-fld., and the blossoms are sometimes larger. Sparaxis is essentially distinguished from Ixia and other allied genera by the subregular perianth, unilateral and arcuate stamens, and scarious lacerated spathe-valves. Although a few plants of sparaxis are occasionally cultivated in America by bulb-fanciers, one may search through many American catalogues without finding them listed. The Dutch bulb-growers offer twenty-five distinct kinds, which is perhaps a quarter of the number of varieties of ixias in cultivation. According to J. G. Baker, there is "only one species in a broad sense, varying indefinitely in the size and coloring of the flowers." For practical purposes Baker recognizes the three species given below; of these the most important and variable is S. tricolor. Sparaxis pulcherrima of the Dutch trade is properly Dierama pulcherrima, Baker. This grows as much as 6 feet high and has pendulous bright blood-purple flowers but apparently with pale rose and perhaps other varieties (also a white variety). It is distinguished by its pendulous flowers with regular perianth, simple style-branches, equilateral stamens, and large bracts which are not laciniate. B.M. 5555. F.S. 17:1810. Gn. 20:588; 44, p. 281. G. 16:386; 29:197. G.L. 27:152. This plant is said by F. W. Burbidge to be "perhaps the most graceful of all the Cape irids." (See Vol. II, page 1007.)

Sparaxis plants

Sparaxis (Harlequin Flower) is a genus in the family Iridaceae with about 13 species endemic to Cape Province, South Africa.

All are perennials that grow during the wet winter season, flower in spring and survive underground as dormant corms over summer. Their conspicuous flowers have six tepals, which in most species are equal in size and shape.

Sparaxis bulbifera is the commonest in cultivation, with flowers from cream to yellow or purple. S. grandiflora is a similar but larger plant. Sparaxis tricolor has bright red flowers with yellow and black centres. Many named hybrid cultivars were bred from S. bulbifera and S. tricolor.

A group of species with asymmetrical flowers marked in mauve and yellow, including Sparaxis variegata and Sparaxis villosa, was formerly treated as the genus Synnotia.
