Skylark, this is one of your declined proposals:
Genus: Begonia
Species: (begonia x hiemalis)
Cultivar: Dragone rosewood
Common: winter flowering begonia
Tradename: red fox (dummen)
Series: dragone
You should have initial capped all of the words but the species name, the species should not have been enclosed in parentheses, and you should have left the tradename line blank. The Dummen Group is the breeder, and Red Fox is one of the group's licensors. Neither of these is the trade name of the plant. The plant has no trade name because neither Dragone nor Rosewood is followed by a trademark symbol.
