Pelargonium is a genus of flowering plants which includes about 200 species of perennials, succulents, and shrubs, commonly known as geraniums or storksbills. Confusingly, Geranium is the correct botanical name of a separate genus of related plants often called Cranesbills. Both genera are in the Family Geraniaceae. They are drought and heat tolerant, but can tolerate only minor frosts. Some species are extremely popular garden plants, grown as bedding plants in temperate regions.

Pelargonium denticulatum is a well branched strongly aromatic plant with sticky finely divided leaves. The leaf margins are irregular and finely dentate with sharply pointed teeth. The leaves are characteristically hard and rigid and are densely covered with glandular hairs. Pelargonium denticulatum with its attractive, strongly scented leaves and pinkish purple flowers is an interesting addition to the mixed herbaceous border, adding texture, fragrance and colour.
