Citronella is a commonly used name for a variety of plants, often referring to members of the genus Cymbopogon, which includes lemongrass. The citronella plants most widely known for their insect-repelling properties are Cymbopogon nardus and Cymbopogon winterianus. These species are often referred to as the "true" citronella plants.
Citronella plants are tropical, perennial grasses. They can grow up to 6 feet tall, and they have long, thin leaves that are typically about 1 inch wide. The plants form large clumps and feature stems that are similar to those of other grass species, although they are somewhat wider.
The leaves of citronella plants have a strong aroma, which is where the plant gets its name. When crushed or brushed against, they release a distinctive citrusy scent that's often described as similar to that of lemongrass, but with a sweeter, more complex fragrance. This scent is also used in the production of citronella oil, which is a popular natural insect repellent.
The oil is extracted through a process of steam distillation from the leaves and stems of the plant. Besides being used as an insect repellent, citronella oil is also used in soaps, candles, and perfumes. However, while citronella plants do have some mosquito-repelling properties when planted in the garden, they're not as effective as the concentrated oil.
As a tropical plant, citronella prefers full sun and well-drained soil. It is not frost-tolerant, so in colder climates, it's often grown in containers that can be moved indoors during winter.
