Common name: Geranium · Pelargonium · Storksbill

Pelargonium is a genus of about 280 species of flowering plants native mostly to South Africa. Long cultivated as the familiar bedding "geranium," it includes zonal, ivy-leaved, and scented-leaved types, valued for their long blooming season and aromatic foliage.

Fun facts

  • The plants commonly sold as "geraniums" are actually pelargoniums; true geraniums are a separate genus of hardy cranesbills.
  • Scented-leaved varieties smell of rose, lemon, peppermint, or even chocolate when their leaves are brushed.

Common problems

    • Let soil dry fully between waterings
    • Use fast-draining potting mix
    • Avoid wetting leaves and stems
    • Move to the brightest available window
    • Pinch tips to encourage bushiness
    • Hang yellow sticky traps nearby
    • Spray undersides with insecticidal soap
    • Water less often in cool weather
    • Improve airflow around the plant
