Viola sagittata

provided by wikipedia EN

Viola sagittata, commonly called the arrowleaf violet,[1] is a species of flowering plant in the violet family (Violaceae). It is native to the eastern North America in Canada and the United States, where it is widespread.[2] It is found in a variety of natural habitats, but is most common in dry, open communities such as prairies, glades, or woodlands, often in sandy or rocky soil.[3][4]

Viola sagittata is an stemless perennial. It can be distinguished from other Viola in its area by its leaves that are much longer than wide, with truncate to subcordate bases.[5] It produces purple flowers in the spring.[3]

Taxonomy

Two varieties are currently recognized.[4][6] They are quite distinct, which has led some taxonomists to consider them to be distinct species.[7] The varieties are:

  • V. sagittata var. ovata - Found primarily in the Appalachian Mountains and Great Lakes area.
  • V. sagittata var. sagittata - Widespread across eastern North America.
