When I read the descriptions of Oxheart carrots last year, they all sounded about like what I had been looking for: short, broad shouldered, does well in clay soils. What the descriptions didn't do was translate all that into a picture. Here are a few that I pulled up today:
If I had known that the mature, ready-to-eat carrots were so short that they were nearly spherical, I would have ordered a different variety. This is one of those little lessons about doing more research before devoting time/space/$ to planting seeds. You'd think that by now I would have learned that lesson very well, but, based on this particular carrot experience, that would seem to not be the case . . .
There are, however, two bits of good news here. The first is that these little carrots are good to eat. The second is that there are lots of them, which helps make up for how little "carrot" is actually in each one.
Also, their very shortness may make these carrots a good variety for people who grow most of their veggies in containers.
