Scented Geraniums

When you’re thinking about your spring containers and considering petunias, impatiens, osteospermum, and liquorice vine, don’t forget about fragrance. Give those big red geraniums a pass this year and find a scented geranium instead. The aromatic leaves come in all flavours, from rose to coconut to lemon to peppermint, which will add another dimension to your patio experience. Scented geranium foliage comes in a range of shapes—some rounded, some like maple leaves, some ferny and finely cut. The flowers are pretty, too, though smaller, paler, and more delicate than the blossoms on more traditional bedding geraniums.

Garden notes

  • The point of having scented geraniums is their fragrance, so plant them near a patio or walkway where you’ll brush by them often.
  • Though the flowers of scented geraniums aren’t as striking as those of other geranium groups, the plants are still valuable in containers, window boxes, and hanging baskets, where they provide a lush green backdrop and the surprise of strongly aromatic foliage.
  • Use dried leaves in potpourris.

Species and cultivars

  • The leaves of P. ‘Attar of Roses’ have such a strong rose scent that they’re often used to supplement actual rose petals in perfumes.
  • P. ‘Clorinda’ has cedar-scented leaves and dark pink flowers.
  • P. crispum has lemon-scented leaves and pale purple flowers.
  • P. grossularoides has coconut-scented leaves and magenta flowers.
