Carrot Gonsenheimer Treib

In general carrots do badly on our very heavy clay, so beyond the odd hopeful row of early Nantes I don't bother. But I recieved a free packet of gonsenheimer treib in a seed order so sowed a row. 
Wow - almost a whole row germinated and in 91 days matured into harvestable roots: I usually get 10% ish!!
The RHS is very dismissive, describing them as "wild" with fruit that is "small hairy and lumpy"! For that reason I only sowed a row. In fact thay have nice smooth conical bright orange roots. The taste test comes tonight.
Of course just before I noticed them I'd filled the remaining space in the root bed with spare kale plants!!
The point of the post? Anyone grown them before? And don't give up on stuff you can't grow because you might find a variety you can

Never heard of them and they don't seem to be for sale in the UK. Sound good.

I never heard of them PP, look forward to the taste test results and maybe a few photos.

I finally remembered to take a photo before cooking the carrots today! 
The taste was not exceptional, but better than most shop bought carrots, and nice enough that I can imagine actually buying some more seed in the future. Although I do have to remember that for us, this summer is excpetionally cool and wet which may be why they've done well.
