Centaurea cyanus
Bachelor's Button, or Cornflower, is an annual plant typically grown outdoors for its vibrant blue, pink, white, or purple flowers. It features slender, grey-green leaves and an upright growth habit, reaching heights of 1 to 3 feet. While admired for its ornamental value and use in cut flower arrangements, it is primarily an outdoor plant that thrives in full sun. People grow it for its attractive flowers that attract pollinators and its ease of cultivation in gardens and fields.
Goatsrue
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.
