De-Mystifying Cucumber Types and Terminology

It is the best article on cucumbers that I ever read. Explains about the different classes like the American, English and Asian. Also difference between pickling and slicers. Talks about greenhouse and parthenocarpic and gynoecious cucumbers. And Beit Alpha cucumbers. I have never heard of Beit Alpha cucumbers until now.

It's a big new world out there. Much more to cucumbers than I ever realised.
