Diantha(die-ANN-thuh)- from dianthus, a type of plant. My grandma knows a lady named this. I think it's gorgeous. Less common and in my opinion prettier than Diane\Diana.
Flowers in the dianthus family are known by different common names-- Carnations, Pinks & Sweet William. Its meaning comes from Di meaning "god [Zeus]" and anthos meaning "flower."
