I have already tried. Thanks.

piski, I've received your email but my reply was sent back. I will try one more time. Perhaps you need to check the email address that you sent me or use another one for future communication.
I was able to get some seeds but I am still interested in yours. I didn't put out a list of seeds that I have to trade. I have various giant sunflower-Craven, Bott's, Martin Reiss strain, etc.
What size can I expect of this variety? Do you know the name? Thanks.
