There are hundreds of varieties of Pelargonium and many are strongly scented.
One of my favourites is the Lemon Scented Geranium (Pelargonium tomentosum); very popular as part of any substantial herb garden mostly because of the lovely strong lemony scent.
It is well loved by insects such as honey bees, bumblebees, butterflies and the like.
Despite the fact that most of the scent will disappear when the leaves are dried it is still popular for cooking within some cultures.
For a nice taste add some fresh leaves to a herbal infusion. Alternatively, infusing the flowers and leaves in cold water over night is a good way to produce a lovely scented water to splash your face with and maybe as a refreshing summer drink? Still a required taste, I might add.
