Tomatoes. I have some, and they're very nice indeed.
I sent away for a free packet of cherry tomato seed from Thompson and Morgan earlier this year. The variety was called
Gartenperle and they have the most wonderful tomato-ey flavour.
They're meant for hanging baskets and such, which I didn't realise, so mine are planted in the greenhouse floor, but they don't seem to mind and are cropping nicely. I think I shall shell out for another packet next year.
