What Is the Citronella Plant?
Citronella plants are scented geraniums. They give off a pleasant, citrusy fragrance when you brush against the leaves or rub them between your fingers. This fragrance naturally discourages mosquitoes, hence the nickname “mosquito plant”.
Citronella plants (s) are often confused with the citronella grass (Cymbopogon nardus).
Citronella grass grows in clumps and is the main source of the commercially extracted citronella oil. The citronella plant, on the other hand, contains only a small percentage of the citronella oil.
Also called the citrosa geranium, the plant has deeply lobed, lacy leaves. Its attractive, double-hued blooms of pink and magenta alone make it worth growing.
Citronella Plant Name and Meaning Explained
The name citronella originates from the French word citronnelle, which means lemon balm, owing to its floral, citrusy aroma.
Citronella plants are a member of the geranium family and symbolize protection, healing, and cleansing.
Good to know: This plant is vase-worthy and can be used as a table centerpiece. Gift citronella plant bouquets to your loved ones as a symbol of friendship or wishes for their well-being.
Does the Citronella Plant Repel Mosquitoes?
Citronella plants are nicknamed as the mosquito plant, so they should typically repel mosquitoes, right? Unfortunately, that’s not entirely the case.
When the leaves of this plant are crushed, they do release minute amounts of citronella oil that has insect-repellent properties.
But the amount of oil released isn’t enough to keep away those pesky mosquitoes. Only after the oil is extracted and distilled does it work as a repellent.
The Bottom Line: So don’t expect a mosquito-free garden picnic just because you planted some citronella plants. That’s not to say you shouldn’t grow them in your garden. They are low-maintenance and delightful to look at. Plus, you can always enjoy their fragrance.
