Shari, the one you should be asking is your local nurseryman.
Nurseries do not make a habit of stocking plants they cant sell. If a plant is hardy in your zone, then you can think your local nursery would have it...or can get it for you.

If they feel a plant is not hardy to that area, they will advise you of that and trust that if you still wish to purchase such an item, they might get it...but give no guarantees.

Rose geraniums are aromatic. The scent helps people with epilepsy. It does very well in our Bush. Alot of people get upset about plants that aren't Native going wild but - The roots aren't deep or invasive, so they're incredibly easy to rip up when we need to clean up the flaura content of the bush. On Molloy Island Gerainums are alowed but only in pots. Also they are the only type of plant-not native to the Island that is are allowed for pots
