Citronella Plant

It is sometimes confused with a scented geranium known as the mosquito plant, Pelargonium Citrosa, which is a hybrid of a geranium and the true citronella plant.

The two plants are often confused because both offer the citronella scent that is said to repel mosquitoes. But the true citronella grass also contains medicinal qualities.

Growing Citronella

The true citronella plant is a perennial clumping grass that can grow to six feet in height. It bears gray-green blades on stems that resemble canes.

Gardeners in zones 10 and below can grow citronella in their landscapes as an ornamental grass. Some shade is tolerated, but full sun will assure healthy growth.

It is useful as a border planting or can be a focal point in a bed of shorter plants. It has a coarse texture and appearance and adds contrast to a bed of flowers or herbs.

Grown in full sun and kept from drying out, with a semi-annual application of nitrogen-rich fertilizer, the plant will thrive.

In colder climates, plant it in a large pot set into the ground and bring indoors to overwinter. Potted plants should have adequate drainage so the plant does not remain wet.

Using the Citronella Plant

Citronella oil is distilled from the leaves of the plant. The oil bears the familiar lemony scent common to commercial citronella oils and candles.

The plant itself does not repel insects as effectively as products containing the essential oil, but it does have an appealing fragrance.

Plant clumps of the grass near sitting areas. Leaves from the plant can also be scatted on decks and porches to spread the scent.

The stalks are commonly used in Asian cooking for seasoning meats, fish, soups and teas.

If grown organically, fresh homegrown leaves can be harvested and eaten raw in salads or added to recipes. As a tea, it relieves congestion, body aches and flu symptoms.

In traditional oriental medicine, citronella grass leaves and stalks have been used to treat fever and digestive issues, as a topical treatment for arthritis, scabies and skin blemishes. It is also a good source of minerals and fiber.

Propagating

Divide the clumps before winter sets in. Dig up a portion of the existing clump and separate into several smaller clumps.

Plant them individually in pots or directly in the ground, depending on your region. To assure new plants for next year, pot some of the clumps and keep them indoors until spring.

Though it may not be an effective insect repellent, its other benefits make the citronella plant worth considering in the landscape.
