I get Burseens from all over. Stout's and The Shady Spot are two of 3 vendors that will start introducing his iris for him starting next year and both have large collections. I am blanking on the third vendor at the moment but know they are friends of Tom's. Superstition has a nice selection, Breezeway has a very affordable collection, Wild Iris Rows has some of the less easy to find like Sensationalizer and I Wuv Woses, and Blue J carries many of his older varieties.
Liz - do all the vendors just tell you what they are getting since you place such big orders?
I had been told the whole story about the future introductions of Burseens but had to keep it a secret for months until the vendors had their final meetings with Tom Burseen and they divided the stock. I think I was told only because it appears that everyone knows my Burseen obsession.
