Beware, Beware!
These are dl that like the black diamond crepe myrtle (remember that one?) are either with or without permission from the hybridizer- being sold as 'something new' or 'exclusive' but are most likely registered already under a different name.
Basically if the database doesn't stick to AHS registers, you will get Plant A registered over and over using names like Plant B! or Plant C or Plant D! and then whalla! You have the same plant listed over and over but no one is aware they are the same thing! There is really no way to ID a dl unless you grow the suspected name right next to it to compare.
