Citronella plant, scientifically known as Pelargonium citrosum, is a type of scented geranium that is often marketed for its purported ability to repel mosquitoes. It’s important to note that this plant is different from the true citronella grass (Cymbopogon nardus or Citronella winterianus), which is the source of citronella oil used in insect repellents.
The citronella plant may add a pleasant fragrance to your garden, its effectiveness as a mosquito repellent may be limited.
