(Just) my opinions:
I like
Linnea and
Poppy very much.
Poppy is more of a gp, though. 9/10 and 8/10 respectively.
Camellia,
Iris, and
Jasmine are all okay. They aren't really my favorites, but they're pretty well established names. 7/10s all around.
I like
Zinnia and
Marigold, but they don't feel very well established. 6/10s.
I like how
Aster looks, but not how it sounds. 3/10
Lunaria and Dianella are too frilly and not well enough established for me. I don't think Lunaria is a very commonly known flower, so it just sounds like a combination of
Luna +
Aria. Similar with Dianella:
Diane +
Ella. 2/10
