Victoria plums, yum. I had a run in with Tesco last year because they weren't stocking any local plums, only the horrid hard purple things from Spain :-(
What ever is in season, so at the moment its strawberries but I cannot touch the winter imports. Soon I will switch to cherries as my favourite and in the autumn its local apples and pears.
Scrivens, my Mum had a Loquat tree in her garden in the middle of London. the fruit are delicious. She brought seeds back from a holiday. I've now got plants grown from fruit from her tree so am hopeful that I will get fruit too.
