About Citronella Plants
Citronella plants, often mistaken for Citronella grass (lemongrass), are a species of flowering subshrubs in the Pelargonium genus. While they share a lemon-like fragrance with Citronella grass, these plants are actually varieties of scented geraniums that release a citronella-like perfume from their crushed leaves. With their attractive foliage and charming flowers, Citronella plants make wonderful additions to various landscape decorations.
Citronella Plants Features: An Overview
Citronella plants belong to the Pelargonium genus, which includes approximately 280 species of shrubs, perennials, and succulents. These herbaceous perennial subshrubs typically reach a height of 18 to 24 inches and a width of 12 to 18 inches. They feature fern-like foliage and evergreen, palmate leaves that emit a fresh, lemon-like scent reminiscent of citronella.
During the blooming season, which spans from late spring to early autumn, Citronella plants produce small clusters of lightly fragrant pink to purple flowers with lavender overtones. These blossoms add a delightful touch of color to any garden or indoor space. Citronella plants also pair well with other plant species, such as roses, chrysanthemums, sunflowers, lavender, and more.
Growing Citronella Plants
One of the many advantages of Citronella plants is their easy-going nature when it comes to environmental and growing requirements. Here are some tips for successfully growing Citronella plants:
Sunlight: Citronella plants thrive under full sunlight exposure. In warmer climates, they can tolerate and even appreciate some afternoon shade.
Climate: Citronella plants are typically hardy in USDA zones 10 and 11. While they can withstand short periods of light frost, it's advisable to protect them during colder winters. These plants prefer tropical climates and perform exceptionally well in hot temperatures.
Soil: Citronella shrubs can tolerate a wide range of soil pH levels, but they thrive in slightly acidic substrates with a pH range of 5.8 to 6.3. Avoid overly nutrient-rich or organic-rich soil, as it can diminish the strength of their fragrance.
Watering: Citronella plants are drought-tolerant and do not enjoy having their roots constantly wet. In humid climates with regular rainfall, you can even skip watering them altogether. However, be mindful of extended periods of dry soil, as they can cause yellowing or browning of the foliage. Water your Citronella plants only when their soil has completely dried out.
Pests and Diseases: Citronella plants are generally resistant to fungal diseases and pests. However, occasional intruders like mealybugs, aphids, or spider mites may appear. If you notice any infestation, handpick the pests and treat your plants with a suitable insecticide or pesticide.
Propagating Citronella Plants
If you're eager to expand your Citronella plant collection or surprise your loved ones with a thoughtful gift, propagation is the way to go. The best method for propagating Citronella plants is through stem cuttings in early spring. Follow these steps for successful propagation:
- Take stem cuttings that are approximately 6 inches long.
- Remove all but the uppermost leaves from the cuttings.
- Dip the cut ends of the stems in rooting hormone for optimal results.
- Fill a container or bed with moist vermiculite and plant the cuttings.
- Keep the substrate moist until the cuttings develop a healthy root system.
- Once the roots are well-established, transplant the baby plants outdoors or into individual pots.
- Provide the same care routine as for mature Citronella plants.
