>>2253465I wish you luck in your endeavor, my friend. I'll keep most of what I suggest to what I've grown and had luck with. I'm in southern hills of the Appalachian mountains, so your probably a little warmer and dryer.
>tomatoesI suggest planting a productive hybrid like big beef for half your tomatoes. That leaves you room for heirlooms but will provide you a nice safety net. For heirloom slicing tomatoes, I really like black krim and kellogs breakfast. Both make some of the best tomato sandwiches you can get. For cherries, my favorite are black cherry. They're so resilient and productive where I live its ridiculous.
>pumpkin/gourdThere are a lot of good winter squash out there, but I've only grown a few. My favorite pumpkin so far is long Island cheese. It smells like a cantaloupe when you cut into it and tastes great. Its also a good keeper. I have a big one from July that we're going to eat for Thanksgiving.
I'd recommend some summer squash, too. Tromboncino is fantastically tasty and productive. Zuchini is also a must, imo.
>berriesI haven't gotten a harvest out of many berries so far. I have several plants i started from seed that will probably take at least another year to produce. One interesting little plant I've gotten berries from is commonly called Dwarf Tamarillo. I call them peach berries because they taste like peaches to me. If you don't get frost where you live, it will turn in to a small tree. If you do get frost, you can grow it as an annual. Stqrt it early inside and it will produce sweet little berries from early summer till fall. Another cool one im growing is kiwi berry. I haven't gotten a harvest yet, but you may want to look into them.
In your climate, id consider figs as well. They can produce the first year and will probably thrive there.
I get most of my seeds from baker creek, but you may need to find a supplier in Europe. Not sure if they ship internationally.
