The Sundial Lupine Project is an undertaking by the BHGC that hopes to re-establish the native sundial lupine (Lupinus perennis) back into Maine.This native plant is no longer found wild in the state, although it has been re-introduced in a few small areas in southern Maine. Our hope is to increase its range in the state with the help of club members by planting seeds in the fall in containers, then transplanting the new plants in spring into pots which can then be available for donating or planting. Handing seeds out in the summer for individuals to plant in the fall will also be utilized.
This native lupine is an essential plant for the Karner Blue butterfly. Information abounds on the web that the Karner Blue had been extirpated from Maine due to habitat loss and loss of the sundial lupine. A USFWS Karner Blue Recovery Plan done in 2003 mentions that a specimen of the Karner Blue was found and recorded during the 1860’s from a site located in the former Norway Barrens in Norway, Maine.
Just recently, in correspondence with Phillip deMaynadier, Ph.D. of the Wildlife Research & Assessment Section of the Maine Department of Inland Fisheries & Wildlife, the presence of the Karner Blue is now in question. As Dr. deMaynadier states “After Mr. John Calhoun, research associate at Florida State Collection of Anthropods, conducted forensic research on the original purported Maine specimen, he concluded that its origin was mistakenly attributed. So, while it is possible that the species occurred here historically, there is no evidence of such.
If the sundial lupine ever gets planted in Maine in enough quantities to support the Karner Blue, maybe in the future the butterfly will reside here. The Karner Blue would have to be introduced and the Maine Dept of Inland Fisheries and Wildlife would have to deem it acceptable before that happened. In the meantime, the sundial lupine does act as a host plant for other Maine butterflies. Those include the eastern tailed blue, gray hairstreak and the clouded sulphur.
Unlike the sundial, the non-native western lupine (Lupinus polyphyllus), which is prolific along Maine’s highways, does not seem to act as a host plant for any of Maine’s butterflies.
