At the start of February, we planted a row of purple carrots and a row of white carrots.
Now, five months on, still no adult sized carrots. The purple carrots turned out orange, round and the size of a grape. The white carrots did turn out white, but resemble pencil stubs. I could eat eat both rows for a snack.
The carrots have been in the ground for twice the amount of time it should take to grow carrots. I would consider this a complete failure except for the fact they happen to be the perfect size snack for a rabbit.
