Everything about Iris Versicolor totally explained
» For the Yellow Flag Iris, see Iris pseudacorus
Iris versicolor, also commonly known as the
Harlequin Blueflag, the
Larger Blue Flag, and other varitations of those names, is a species of
Iris native to North America where it's common in sedge meadows, marshes, and along streambanks and shores.
I. versicolor is a perennial herb, growing 10-80
centimeters high. This iris tends to form large clumps from thick, creeping
rhizomes. The unwinged, erect
stems generally have basal
leaves that are more than 1 cm wide. Leaves are folded on the midribs so that they form an overlapping flat fan. The well developed blue flower has 6 petals and sepals spread out nearly flat and have two forms. The longer sepals are hairless and have a greenish-yellow blotch at their base. The inferior ovary is bluntly angled. Flowers are usually light to deep blue (purple and violet are not uncommon) and bloom during May to July. Fruit is a 3-celled, bluntly angled capsule. The large seeds can be observed floating in fall.
The species has been implicated in several poisoning cases of humans and animals who consumed the
rhizomes, which have been found to contain a
glycoside,
iridin. The
sap can cause
dermatitis in susceptible individuals.
The blue flag is the provincial flower of
Quebec, having replaced the
Madonna lily which isn't native to the province.
