Rosea/ Roseus?

I wrote about these two on my blog. I think they’re pretty usable, Rosea at least, since [name]Rose[/name] is pretty popular as either a fn or mn. What do you guys think?

Oh and how would you guys pronounce Rosea? I would say [name]Rose[/name]- ee- ah but it could be perceived as a variation of [name]Rosie[/name].

Too similar to Rosacea.
