Wild Perennial Lupine (Lupinus perennis)

Wild Perennial Lupine produces flower clusters that can reach up to eight inches in length. The flowers are generally blue but can vary in shade from the bottom to the top of the cluster. Each flower has a pea-like shape, consisting of a banner petal, wing petals, and a keel petal. The plant's stems start off hairy but tend to become smoother as they mature.
