While colored carrots seem to be new to home gardens, they have been around for centuries. In fact, the purple carrot has been around for at least 1,000 years. After losing out to the more popular orange carrots long ago, purple carrots have been rediscovered. Kids will love them as a colorful snack. Besides being high in vitamin A, purple carrots contain anthocyanin (an antioxidant).

Growing Info
Harvesting: For best flavor and texture, harvest carrots any time before, and until they reach their optimal size. Peak harvest period lasts about 3 weeks, longer in the fall. Late summer-sown carrots are sweetened after having been kissed by light frost; however, harvest before soil freezes, which may destroy the crop. In USDA zone 5 or warmer, carrots can be left in the ground for storage provided they are heavily mulched; harvest as needed on days the ground is not frozen.

I planted these last year and sadly this is the only picture I got we ate them so fast! They looked so pretty, tasted amazing, and had the best germination out of all of the other carrot types I planted :) Can't wait to have more again this year!

The germination rate was perfect. They took very well and are growing very well.

What else? Poor germination. I sprinkled out a whole packet of Shin Kuroda in a different part of the same bed and the Shin Kuroda are doing great. I have four of these purple carrots that actually germinated out of the entire packet.
