I got some from freshops 2 years ago also bought some on ebay - seasonal though but watch about planting time in the east search for hop rhizomes (sp?) check my spelling.
I grow cascade, crystal, liberty and saz in PA to be honest the cascade and crystal are the only producers the others just bine up and look nice for shade. some will do better than others where every you live. I get a handfull of ouces a year (small pots) and make a fresh dry hopped ipa or something.
