Well, it's apparently closed for 2012... but I was really surprised to find out SPCNI had their own seed exchange. The photos are jaw-dropping! http://pacificcoastiris.org/seedex/… SIGNA's seed exchange is in full swing right now. And the Aril Society International just closed their seed exchange. That makes 3 iris-based seed exchanges I know of... oh wait, the British Iris Society has one too... so that's 4. Does anyone know of any others? Dennis in Cincinnati (an iris nut)
