How can I find out whether 2 roses are the same, and what the parents of a
rose are? The rose is from the Jackson & Perkins catalog, Heaven on Earth.
KORravreli, which I assume is Kordes. On the Kordes website I found a very
similar-looking rose called Sangerhauser Jubilaumsrose. I am curious
whether they are the same, and the parents of Heaven on Earth. I checked
the registration list on ARS.org and didn't find it, nor is it in helpefind
yet. Thanks.
