it could be, but people will think it's a bit old fashion, so maybe think about a new one instead..?

it is a good name for girl, a lot of girl use it as name.

tbh, not a good choice... sounds like a toy 's name from last century....

Thank you all for your precious answers, they helped a lot :)

hmmm my advice is don't use 花 as your name. as Creek and percy mentioned, 玉花 and 翠花 are mostly used for countryside girls at least 20 years ago. No Chinese would name themself as "翠花“ believe me or not
