When I was a Ph.D teaching environmental sciences here at Santa Cruz, I had a big garden outside my house. I had invited several friends to play soccer in my back yard. One of the graduate students, who was Dutch, brought her husband along to the soccer game. He represented a large Dutch seed grower, and after looking around my garden plot, he told me that he had a lot of European varieties that were bred for fresh eating qualities rather than commercial purposes. I grew them, thought they were wonderful, and thought that other gardeners would enjoy them as much as I did and that's how I got started.
Tomatoes are always popular but unusual varieties and hierlooms have become something of a trend.
For example, pink Japanese tomatoes are being ordered by our customers. Also, eggplant, especially the quick cooking varieties such as Asian Bride, have gained interest lately. The hotter, the better. In fact, that's another food trend, very spicy foods. That requires a little timing on your part.
