Early maturing purple annual. Colorado Star was specifically bred for annual production from seed. Very early maturing. The 1-3′ tall plants vary from upright to prostrate, but all produce high yields of purple to greenish-purple buds. Typically 1-3 primary buds are produced that are 2 1/2-3 1/2″ in diameter followed by 5-7 secondary buds ranging from 2-2 1/2″ diameter. Developed by Keith Mayberry, who also bred Imperial Star. Plants are spiny. Perennial in Zone 7 and warmer, otherwise treat as an annual. NOTE: Amount of purpling may vary from plant to plant; some buds will be all purple, while others only show purple-tinged bracts.
