I noticed that all the pelargoniums are listed as "Scented-leaved Geranium (Pelargonium)". Not all of them are scented though. The Ivy (Pelargonium x peltatum), Three-colored Geranium (Pelargonium tricolor), Martha Washington Geranium (Pelargonium domesticum) and Zonal or Fish (Pelargonium x hortorum) do not fit in the scented category.
