Wild lupine begins to grow in the early spring and flowers in May. Blooms typically last for a few weeks. Flowers are usually blue, but can also be shades of pinks, purples and white. The flower spikes can stand up to 7" standing above the leaves. The flowers turn to peapod-like seed pods as the season progresses. The outer shell is fuzzy in appearance and is about 2" long. Each pod contains between 10 - 20 seeds.

In addition to its pure beauty that we enjoy, the karner blue butterfly (Lycaeides melissais) is reliant on lupine as the caterpillar will only feed on the lupine plant.
