Dont bother with Asparagus, or maybe do if you have a lot of growing space.
Have a look around at all the fruit and veg you like when you walk around a supermarket but dont buy because you always say “How Much”
Growing potatoes go for unusual varieties, again expensive, I grow Jerusalem artichokes as well as artichokes. Try Garlic but get it in now. Cabbage, fennel, hamburg parsley, salsify, purple top turnips are some of my favourites as easy to grow and store
