These seeds were collected from Crotalaria spectabilis, also known as Rattlebox, Showy Rattlepod, and Cats Bell. These annuals like to live in full sun where they grow to about 2 feet tall. The bright yellow and gold flowers are out from the late summer until the middle of the winter where they attract a wide variety of birds, bees, and butterflies. Crotalaria in general are larval host plants for the Bella Moth. This annual can be grown in any USDA Hardiness Zone and is a tender perennial in Zones 9 to 11.
