This 'rose scented geranium' is not that common in the garden shops that sell scented pelargoniums. It has slightly wooly leaves and might be Pelargonium capitatum sometimes called "Attar of Roses". I doubt it is the rose scented Pelargonium graveolens which is much more common in the gardens of this geographical area, the Pacific north coast of California, as the leaves are not lacily lobed. When the leaves are distilled, they give up the most lovely rosy scented floral water, the hydrosol. Every winter when there is a bit of snow, many of them die ulesss we remember to throw a light tarp over them in the evenings.
After the really cold winter we had a few years ago, it's taken many cuttings and until now for there to be enough to distill in my funny old pot still that we set on the top of the stove - one large grocery bag packed full of leaves.
I've never tried growing this plant indoors, though some sources say they do fine in front of a bright window. I think I'll take some cuttings before the night freeze comes which means I should do this tomorrow as their has been frost in the mornings and otherwise quite cold.
If I am able to keep the bulk of the rose geraniums from freezing this winter, next spring we'll be able to distill some hydrosol, perhaps a quart or two.
