Rose cultivars in Category:Roses at Roseraie de Bagatelle

This query makes the assumption that any category starting with "Rosa_'" is a rose cultivar category. This is true at the moment, but could concievably become false. Also, if any cultivars don't use this scheme, it will fail.

Some of the results are also Wikimedia category QIDs rather than rose cultivar QIDs directly; following the category's main topic links requires a different query.
