I have been thinking for years that my 'Royal Eventide' was registered as a single, but that it always looked more like a double. I just checked my PlantStep program and it does list it as a double. So I rechecked the database here and it is listed still as a single, but the AHS site "now" shows it as a double. It might have been that way all along, or it might have been changed. My question is should it be listed here in the database as a single or as a double?
