Lardman;
I see you are trying Purple Ukraine. Did these last year and they are huge ugly plants with ferny leaves. The fruit have 2 completely different tastes; pick them young (greenish brown, firm) they have a great texture and a very nice, quite acid, taste. Leave them to go darker purple and they get really sweet but go a bit soft for me (make a great, if odd coloured, tomato sauce).
