Barbe Bleue (see photo) is a dark, velvety red pelargonium peltatum.
They are more difficult to overwinter than the zonal varieties.
I lost mine a few years ago.
There are a few new introduction that are similar in colour but are more vigorous.
One variety I would recommend is the Royal Dark Burgundy
Barbe Bleue will be added in the photo book on pelargoniums.
