Galega officinalis

Goatsrue (Galega officinalis) is a perennial herbaceous plant known for its clusters of pea-like flowers, typically lavender, pink, or white. It grows to a height of 1-1.5 meters. Primarily an outdoor plant, it is cultivated for forage and, historically, for medicinal purposes. It is not typically grown indoors due to its size, light requirements, and potential for aggressive spread via rhizomes. People might grow it outdoors for its attractive flowers and as a nitrogen-fixing plant.
