Lemon geranium (Pelargonium crispum) is a tender perennial aromatic herb in the Geraniaceae family, native to South Africa. It bears small, crisped leaves with a bright lemon fragrance, and the leaves are the main part used in household and herbal preparations.

Traditionally, lemon-scented geraniums have been used in cooling teas, bath herbs, potpourri, and natural household blends. They are especially appreciated for their lively scent and ease of cultivation in containers.
