Hi Johnboy,
Thank you for your replie. The variety of seed I used was from Suttons and it only says 'Cabbage, April, for Spring and Autumn harvest'
The picture shows large outer leaves, with a conical heart, like a tenderheart cabbage.
Perhaps I will have to be more patient.

I planted out last autumn some spring cabbage, some in the greenhouse (unheated) and some under clouches, the greenhouse ones have grown loads of leaf, but no hearts. the ones in the ground are nothing to write home about!! Where have I gone wrong?

Hi Mike,
Have never grown celeriac, but would love to give it a try. Which would be good for a small space that I have left, President or Prinz?
