I planted three types of carrots this year. Two orange varieties and a purple one. The orange heirloom called "Oxheart" is produces a 6 inch root, 4 inches wide and over 1 pound! I'm looking forwar to this. It looks like I'll need to do some serious thinning of all of the carrots. I tried to scatter the seed thinly this year, but still a million little plants.
