It is a very hardy variety of Kohlrabi. Grew best out of three different varieties in heavy clay test gardens. The other two varieties were Gourmet White and Early Vienna.

This is one of the hybrids that I have tried. The only advantage noted is that it is about a week to 10 days earlier than White Vienna. It is touted as being resistent to disease, but I have never had a problem with diseases. Very similar to white Vienna otherwise.
