I had a disappointment yesterday.
My first lupine seeds germinated – it's such an exciting moment when one sees the soil pushed aside by the curl of an emerging cotyledon (the first leaf)!
I had planned for some time to write about the importance of growing Wild Lupines, which are the host plant for three butterflies classified as extirpated in Ontario. Extirpated means that they once lived in the wild here, that they still survive somewhere else in the world, but no longer eist in the wild in this province.
The Karner Blue (
Plebejus melissa samuelis) and the Frosted Elfin (
Callophrys irus) rely exclusively on the Wild Lupine, it is the only plant their caterpillars are able to digest. The Wild Lupine is also the host plant for the Eastern Persius Duskywing (
Erynnis persius persius), although this butterfly can use Wild or False Indigo (
Baptisia australis) for food. In all three cases the last sightings were in the 1980s, in two areas in southwestern Ontario.
My seed has been collected from my own plants, the parent plant having been grown from seed labelled
Lupinus perennis (Eastern, Wild or Sundial Lupine) that I purchased a few years ago from a large Ontario-based seed company.
