Lupine is one of the earliest blooming wildflowers that we see around here. They usually begin to bloom in May and most of the flowers are gone before the end of June. They are also usually one of the first wildflowers to grow into a new area, such as a field that has been cleared or after a forest fire. Unfortunately it does not take them long to be choked out by other plants and grasses. So as our fire protection and suppression techniques have gotten better the amount of lupine out in the wild has decreased. Which has hurt species like the endangered Karner blue butterfly.
