60 days — Thanks to the work of Dr. Philipp Simon and staff at the USDA Agricultural Research Station in Madison, Wisconsin, a whole rainbow of colored carrots have become available since the early 2000s. Although purple colored carrots have been cultivated in Afghanistan, Turkey and Middle East since about 900 A.D., this variety was released in 2005.
'Cosmic Purple' plants are large, reaching fifteen to twenty-four inches in height, and produce carrots that are bright purple in color on the outside and orange on the inside. They make an interesting, tasty, and sweet addition to a veggie platter. 'Cosmic Purple' is a six to eight inch long, Danvers-type carrot.
According to the USDA
, purple carrots contain the pigments (and antioxidants) anthocyanin
, beta carotene and alpha carotene which they report as benefiting health by helping to prevent heart disease and strokes. Each packet contains one gram, which is approximately 650 seeds.
