Iris brevicaulis is a species in the genus Iris, it is also in the subgenus Limniris and in the series Hexagonae. It is a rhizomatous perennial, from North America. It has bright green, glossy long leaves, a long zig-zagged stem and 3–6 flowers per stem, which come in blue shades from violet-blue, to lavender, to purple-blue, to bright blue to blue, and pale blue.
The Louisiana irises generally all have similar cultivation requirements. Iris brevicaulis needs acidic soils (ph level of 6.5) with a high organic and high fertility content. It prefers full sun but can tolerate partial shade and prefers wet soils it can tolerate well drained soil.
For best flowering, moisture is essential during late autumn, winter and spring times (October to May), when the plant starts to grow new leaves. They can be given a light feed between autumn and spring, if needed.
Like many other irises, most parts of the plant are poisonous (rhizome and leaves), if mistakenly ingested can cause stomach pains and vomiting. Also handling the plant may cause a skin irritation or an allergic reaction. The rhizomes (thickened roots) of Iris brevicaulis contain poison. If mistakenly eaten it could cause nausea, vomiting, abdominal pain, diarrhoea and an elevated temperature.
The roots, seeds and plant sap can also cause skin irritation if touched.
Iris brevicaulis is the hardiest and most adaptable of all the Louisiana irises. Occurring a wide range of habitats.
