Reseda lutea — yellow upright mignonette

Copyright: various copyright holders. To reuse an image, please click it to see who you will need to contact.

Facts

Yellow upright mignonette is widely introduced in our region and throughout North America, and its native range extends from Great Britain to west Asia. It gets its genus name, "Reseda" from the Latin word "to calm," because the plant has sedative properties. "Lutea" means "yellow," and refers to its flowers and also the potential to produce a yellow dye. The showy spires of flowers attract bees and butterflies.
