Including Campanula, Orchid, Crowfoot Grass, Coltsfoot, and various flowers.
Flowers are a general ingredient in Mini World: CREATA for cooking and crafting. All items in this category are considered flowers, aren't distinct from each other, and will produce the same foods and craft the same items (except recipes which require a specific type of flower).
Neither Void Campanulas nor Void Flowers are classified as flowers, most likely unintentionally.
