Virginia Meadow-beauty (Rhexia virginica)

Life history

Species overview

Virginia Meadow-beauty (Rhexia virginica), a Wisconsin Special Concern plant, is found in wet, acid ditches, as well as in ponds and lakes with fluctuating water levels in the bed of Glacial Lake Wisconsin. Blooming occurs early July through late August; fruiting occurs late July through early September. The optimal identification period for this species is late June through late September.

Habitats and landscapes

The Natural Heritage Inventory has developed scores indicating the degree to which each of Wisconsin's rare plant species is associated with a particular natural community or ecological landscape. This information is similar to that found in the Wildlife Action Plan for animals. As this is a work in progress, we welcome your suggestions and feedback.

Species guidance

The Endangered Resources Program has developed avoidance measures and management guidelines for plants on the Natural Heritage Working List. These are a work in progress, and we welcome your suggestions and feedback. Sources used in developing this information can be found here.

Avoidance measures

These are specific actions designed to avoid "take" (mortality) of this species.

Avoid known individual plant locations and conduct operations elsewhere when they are least likely to cause damage. Ideally, this would involve frozen, snow-covered ground. However, in areas of the state where frozen conditions are unreliable, very dry soils late in the growing season might be the best available alternative. Consult with a biologist, if needed.
Avoid broadcast spraying of herbicides; use care with spot spraying.
