PROTECTING WISCONSIN'S BIODIVERSITY

Blooming occurs late-July through late-August, fruiting occurs early-August through early-September.

Perennial. The optimal identification period for this species is late-July through August.

Mullein foxglove is hemiparasitic. Associated species include Quercus alba, Q rubra, Q muhlenbergii, Rhus glabra, Ulmus americana, Cornus foemina, Sorghastrum nutans, Liatris aspera, Coreopsis palmata, Euphorbia corollata, Rudbeckia hirta, Andropogon gerardii, Solidago rigida, S ulmifolia.

Mullein foxglove prefers moist, sometimes calcareous soils and is found in oak forests and openings, often with dolomite near the surface.

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 and use care with spot spraying.

Avoid site preparation that heavily disturbs herbaceous ground layer and soil, including bulldozing and furrowing, as well as grubbing and stump removal.

This species is hemiparasitic, avoid disturbance to trees for which this species is hemiparasitic along with frequent or persistent disturbance to the herbaceous groundlayer.

Prescribed burns and/or brushing may be beneficial, dependent on local site conditions and burn frequency. Rotational burns with annual unburned refugia may be preferred.

Maintain and restore open habitat through selective clearing and brushing.

Species of Greatest Conservation Need (SGCN) are associated with habitats (or natural communities) and places on the landscape. Understanding relationships among SGCN, natural communities and ecological landscapes help us make decisions about issues affecting SGCN and their habitat and how to respond.

Conservation actions respond to issues or threats, which adversely affect species of greatest conservation need (SGCN) or their habitats. Besides actions such as restoring wetlands or planting resilient tree species in northern communities, research, surveys and monitoring are also among conservation actions described in the Wisconsin Wildlife Action Plan because lack of information can threaten our ability to successfully preserve and care for natural resources.
