It typically blooms in late spring with 3-6” long, showy flowers that have six petals (three upper petals and three lower petals) in shades of blue, blue-violet or white. Each blossom has a yellow blotch at the base of its lower petals. Narrow, sword-like, leaves (to 12” long) arise from the bulbs and clumps. Flowers are followed by narrowly ovoid seed capsules. Genus name comes from the Greek word xiphos meaning sword in reference to plant leaf shape. Specific epithet comes from the Latin words iris meaning rainbow and folium meaning leaf in reference to plant leaf shape.

Xiphoceras

Xiphoceras is a small genus of just two species in the family Asparagaceae, subfamily Scilloideae. The name is derived from the Greek xiphos, meaning sword, and ceras, meaning horn, referring to the shape of the inflorescence. Both species are native to southwest China.

Xiphoceras longiflorum is the taller of the two species, growing to 60 cm (24 in) tall. The leaves are strap-like, up to 15 cm (6 in) long and 1 cm (0.4 in) wide. The flowers are borne in a dense raceme at the top of the stem, each flower stalk up to 10 cm (4 in) long. The six tepals are white, narrowly lanceolate, 6–8 mm (0.24–0.31 in) long and 2 mm (0.08 in) wide; they Reflexed back away from the ovary so that the stamens and style project prominently.

Xiphoceras Zhongdianense is a smaller plant, growing to just 30 cm (12 in) tall with narrower leaves up to 8 cm (3 in) long and 0.5 cm (0.2 in) wide. The flowers are similarly arranged but only 4–5 mm (0.16–0.20 in) long with narrower tepals only 1 mm (0.04 in) wide which barely reflexed at anthesis so that the stamens project only slightly beyond them; this species also differs by being entirely glabrous apart from some ciliate leaf margins.
