Wow Leslie, you have a wonderful collection of Burseen irises. I think you deserve the title of ATP "Queen of Burseen"!
Thanks for the information on your sources.
I'd like to add a few more Burseen irises this year.
Arlyn, I had never heard of Matthew's Irises before. I gather they specialize in the historics. From your review it looks like he is great to work with! No website though...makes it a little harder to find out what he carries.
