I planted these (Central Mass/5b) last year after years of looking for them. Mine we plagued by a rabbit feeding off the green tops until I fenced them off in mid summer. They recovered and became late season carrots.
The tend to grow inconsistent sizes in my raised beds, but healthy and no signs of worms at all which I have had with other varieties.
Dug/ate them all fall and through new years, literally pitchforking them up with frozen chunks of soil! I did take care to thickly mulch with dead leaves in mid fall.
Taste is adequate imo, cold-dug taste best. These are Champs for stews, soupsing, hold up to cooking and great meaty texture.
There are definitely better carrots in terms of growth, taste etc. etc., but these are a total hoot to grow.
