GENUS INDEX

GENUS CODE: IRIS
GENUS SCIENTIFIC: Iris
GENUS AUTHORITY: L.
GENUS COMMON: Iris
GENUS SUMMARY: A genus of about 225 species, herbs, of Eurasia, n. Africa, and North America. Wilson (2004) suggests that Belamcanda is phylogenetically nested within Iris and should be included there; Goldblatt & Mabberley (2005) make the appropriate nomenclatural combination. Alternatively, Iris may be broken up into multiple genera (Mavrodiev et al. 2014; Crespo, Martínez-Azorín, & Mavrodiev 2015).
GENUS IDENTIFICATION: Identification notes: the petals are usually erect, smaller than the petaloid sepals (which are brightly colored, generally reflexed, and marked with a signal). The styles are also petaloid, arched over the sepals, and 2-cleft at the tip (except in I. domestica).

NCBG DESCRIPTIVES

INTRO: Low-growing, rhizomatous and colonial perennial of moist (and less often, dry) forests, rich woods, road banks and stream banks.
STEMS: Stems consist of branching, horizontal rhizomes at soil surface; a short flowering stalk, with leaves clustered at the base, arises from rhizome.
LEAVES: Leaves overlapping and clustered at base of flowering stalk, linear to lance-shaped, to 6 in. long and 1 in. wide, arching, smooth.
INFLORESCENCE:
FLOWERS: Flowers typically solitary (occasionally 2) at top of stalk; pale blue to purplish; to 5 in. wide; consisting of 3 spreading, ornate, petal-like sepals and 3 smaller, spreading petals; sepals are marked with a white or yellow patch outlined in purple and a toothed, yellow ridge.

Plant Sale Text: Ethereal flowers open over a two-week period. Dwarf crested iris is an attractive groundcover spring through fall. In the wild, this perennial is seen on wooded slopes, bluffs and ravines. Its native range includes areas from Maryland south to Georgia. Dwarf crested iris is an excellent choice for the rock garden, the foreground of a perennial border, or the woodland garden. This species is drought-tolerant once it has become established. It prefers slopes with partial sun. The Iris genus supports up to 12 lepidoptera species.
