Dalia (DA-lee-a).
Dahlia is pronounced DAY-lee-a where I live (not sure why since there's clearly an H in there. Perhaps whoever designed that pronunciation was thinking of the word "dale", which is a cognate of the Swedish Dahl/dal.), and I don't particularly like it.
Dalia looks more international.
Using it to commemorate
Salvador Dali would be cool. I mean, he designed the Chupa Chups logo.
