A related group of plants, in the same family of Geraniaceae, has the actual Latin name Geranium, which causes some confusion. But plants in the genus Geranium are typically perennial and look quite different. Long ago they were all in the genus Geranium, until the 1700s when some were separated into the genus Pelargonium.

Scented geraniums are actually a myriad of species, cultivars, and hybrids, each with a distinctive aroma to the foliage. Especially popular with herb gardeners, scented geraniums can smell like almonds, apples, coconut, lemons, roses, nutmeg, peppermint, strawberries, chocolate, or even Old Spice cologne. The rose-scented ones have been important in the perfume industry. And many find their way into jellies and iced teas as flavorings.

Though the flowers are usually more wispy than the Zonals, Regals, and ivy-leaved types, scented geraniums have a remarkable array of foliage forms: puckered, curled, or rounded, resembling ferns, oak leaves, or grape leaves, with textures from velvety to coarse to sticky.
