Cubelium concolor (synonym Hybanthus concolor), commonly known as eastern green violet,[2] is a flowering plant in the violet family (Violaceae). It is native to eastern North America,[3] where it ranges from Ontario south to Florida, and from Vermont west to Kansas and Oklahoma.[1]

Description

[edit]

Green violet is a shrub-like herb that grows to a height of 30 cm to 1 m. Its inconspicuous flowers are small, close to the stem, and green.[4] It blooms from May to June in Ontario and from April to June in Connecticut.

Habitat

[edit]

The natural habitat of Cubelium concolor is in nutrient rich, calcareous forests and woodlands, typically in mesic or bottomland conditions.[5] It is found less frequently in dry forests and glades.[5][6] It is a fairly conservative species, and is only found in areas with an intact native herbaceous layer.[7]

Most of the Canadian populations are located along the Niagara Escarpment, a prime habitat for green violet.
