This grouping is ours, not the USPTO’s. A plant patent records a botanical genus; it never says “rose”. We group genus by genus, which means the grouping is only as good as that judgement — and a genus that spans two kinds appears under both. For the precise answer, use genus.
A patent expiring frees the plant, not the name. The cultivar name is always safe to use; a trade name may still be a live trademark. See what you may call it.
