Sorry for any repeats. They’re all botanical words or names but not all floral. I’m copying and pasting the above list so I’m not sure how it will display, but [name_u]Vetiver[/name_u], [name_f]Allium[/name_f], [name_u]Mulberry[/name_u], [name_m]Vitis[/name_m] and [name_m]Valerian[/name_m] are the ones listed on Nameberry that can be looked up.
