While digging out some Blue Moon Sibs, I found non PBF bearded iris. They might be more At First Sight. Nothing bloomed there this spring. Whatever they are, they need separating. Of course, old properties are funny. The more one digs, the more old plants that have been dormant for years, keep coming up.
My cousin still owns the 3 decker apartment house my grandparents bought in 1909. As she digs more and more, my grandmother's plants keep coming up. My grandmother has been gone since 1945.
