You possibly can generally discover P. virginiana in moist ditches rising cheek-to-jowl with cattails, sedges, and tall grasses.

Koether hasn’t had a lot luck rising it and Angell notes “it’s not as delicate or good however you get among the identical feeling because the native, straight species.” Norris has each Physostegia virginiana and P. angustifolia, which is native to the central United States, in his backyard and says, “P. angustifolia has been comparatively much less aggressive than P. virginiana in my expertise, and its paler flowers add an ethereal high quality to the backyard.” Koether provides, “The renewed curiosity on this plant is thrilling.
