Dear members!
I'd like to buy seeds of any cold hardy Citrus and hybrids.
If you can sell something please let me know.
Thank you in advance.
Anton.

You are in zone 6a, if you are planning on growing them in the ground not much will survive except Trifoliata and some of it's crosses.

Thank you for the reply.
Yes, it is too cold here for the Citrus but I want to try with protection and I want try to get new forms by hybridization. It is very difficult to find seeds of cold hardy forms here in Russia... cold country with very little subtropical territories near Sochi.
Poncirus is completely hardy in my garden (except southern clones).
I live in mountains and it is additional difficulty. But on the other hand it is possibility for reception of new forms, selections. Changes of temperature within day-night gives interesting results.

I have some Sudachi fruit left which is pretty hardy. If you want some seeds PM me your mailing address & I can send some out next week.

Thank you very much.
