Along with color, pattern, flower shape, and nectar, many flowers use fragrance to attract pollinating insects. Plants with aromatic foliage contain scented essential oils that help protect the plants by repelling or even killing insects and microbes like bacteria. Humans use plant essential oils for perfumes, flavorings, natural insect repellents, medicinal purposes, and in aromatherapy.
