Description of Lupine (Lupinus perennis)
Lupine (Lupinus perennis), a member of the Fabaceae (Bean Family), is a herbaceous perennial, that grows to 3 feet tall and blooms in the spring and summer with blue/purple flowers. Lupine has been in decline due to loss of habitat and fragmentation leading to the rarity of the Karner Blue butterfly, which is dependent on it.
