I have a cultivar called Highland Tower that was hybridized here in Michigan by the late Mr. Toll. The AHS has it listed as a dip but it is definitely a tet. I contacted the AHS about it and they said it could only be changed by the hybridizer. That is impossible because he is deceased. Meanwhile, I continue to get tons of tet crosses from it. It was listed in his catalog as a tet and I have the page from the catalog to prove it.
