Bastard Pennyroyal (Trichostema dichotomum)
Bastard Pennyroyal is an annual plant with small flowers that are an important nectar source for native bees (ncbg.unc.edu). When it comes to other insect interactions, I had a hard time finding more information. Bastard Pennyroyal is considered threatened in Michigan, so while you may not be preserving the plant that was once here, you are creating habitat for all the species that may need it for survival (mnfi.anr.msu.edu).
