I forgot to show you these photos about great variety of different citrus fruis. Sincerely I've never seen many of them, from these on the photo and do not know the names. The biggest, citron is maybe it's name in english, grows here in our zone, some people have them, than mandarines and oranges. The others I don't know what they are.
Except these you see on the photo I know one other citrus plant -feijoa but I did not see it there.
