Origin
Roselia could have simply been originated as a nymph, or a fairy. Even simpler, Roselia could have just been based off of two roses. Though in actuality, there are no such things as blue roses. Although since before Pokemon Ruby and Sapphire's release, scientists were and is still working on making the Blue Girl Rose actually blue. In fact some roses are actually blue, but they are genetically altered.

Name Origin
Roselia's name could have originated from the two words, "Rose" and "Azalea". The azaleas could have come from the fact that some azaleas are blue, referring to the left rose.
