Lupine (Lupinus sp.) is an herbaceous perennial plant from the legume family (Fabaceae). All pea plants have a typical flower shape of two lateral wings and two fused lower petals that form a “keel”. They are easily recognized by their palmate leaf shape (divided into many lobes, like a hand with five fingers). The flowers are vivid in blue and purple and are produced in dense or open whorls. The fruit is a pod containing several seeds. Lupine improves the soil by converted nitrogen in the air to nitrogen in the soil (which other plants can then use for growth).
