I actually really like
Primrose!! And even BEFORE the Hunger Games trend :) I think you're right in that most people dislike the "prim" part. When I posted about it before I mentioned that I actually LIKE the nn Prim and most people said that's what turned them off of it. I think most flower names are already viewed as very "sweet" so I imagine the "prim" part really puts the saccharinity (is that a word?) over the top and positions the name as more "fantasy" than "usable"
I like both
Meadow and
Primrose but I think I'd actually pick
Primrose here.
Primrose Oona is my go-to combo :)
