Citronella vs Vinca Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Citronella
Cymbopogon nardus or Cymbopogon winterianus
Citronella is a perennial clumping grass known for its distinct citrusy scent, primarily due to the presence of citronellal and geraniol in its leaves. It typically grows to a height of 3-6 feet. It's primarily grown outdoors for its mosquito-repelling properties, although the effectiveness is debated and requires crushing the leaves to release the oils. It is not naturally an indoor plant and requires very specific conditions to thrive indoors.
Vinca
Vinca minor
Vinca minor, commonly known as Common Periwinkle, is a trailing, evergreen perennial vine often used as a ground cover. It features glossy, dark green, ovate leaves and produces small, five-petaled, blue-violet flowers in spring and sporadically throughout the growing season. While it can be grown in containers, it is primarily an outdoor plant valued for its ability to quickly spread and suppress weeds. People grow it for erosion control, ground cover, and its attractive foliage and flowers. It is not naturally an indoor plant and presents challenges when grown indoors.

❓ Frequently Asked Questions — Comparing These Plants
Citronella
What are the light requirements for Citronella?
Citronella plants need a good amount of sunlight to thrive. Aim for at least 6 hours of direct sunlight per day for optimal growth and mosquito-repelling potency. If growing indoors, place the plant near a sunny window, preferably south-facing. If natural light is insufficient, supplement with grow lights.
How do I care for Citronella?
Citronella plants thrive in well-draining soil and prefer full sun to partial shade. Water regularly, allowing the soil to dry slightly between waterings. Avoid overwatering, which can lead to root rot. Fertilize every 4-6 weeks during the growing season (spring and summer) with a balanced fertilizer to promote healthy growth and flowering.
How do I propagate Citronella?
Citronella can be propagated through several methods. Division involves separating the plant into smaller clumps and repotting them. Stem cuttings can be taken from healthy stems and rooted in water or soil. Keikis, or baby plants, sometimes form on mature plants and can be carefully removed and potted.
Vinca
What are the light requirements for Vinca?
Vinca thrives in full sun, requiring at least six hours of direct sunlight per day to produce abundant blooms. However, it can tolerate partial shade, especially in hotter climates, where afternoon shade can prevent scorching. When grown indoors, place Vinca near a sunny window, such as a south-facing window, to maximize light exposure. If natural light is insufficient, consider supplementing with grow lights to ensure adequate light levels. Insufficient light can lead to leggy growth and reduced flowering. Rotate the plant regularly to ensure even light exposure on all sides. Observe the plant’s growth and adjust its location as needed to optimize light conditions. Remember that too much direct sunlight can also be harmful, so monitor for signs of leaf burn.
How do I care for Vinca?
Vinca is a relatively low-maintenance plant, making it ideal for beginners. Plant in well-draining soil and provide full sun to partial shade. Water thoroughly when the top inch of soil feels dry, but avoid overwatering, which can lead to root rot. Fertilize monthly during the growing season (spring and summer) with a balanced fertilizer or a bloom-boosting formula to encourage abundant flowering. Deadhead spent blooms regularly to promote continuous blooming. In colder climates, Vinca is often grown as an annual. In warmer climates, it can be a perennial. Protect from frost in colder regions. Prune lightly in the early spring to maintain shape and remove any dead or damaged growth. Monitor for pests such as aphids and spider mites, and treat as needed. Provide good air circulation to prevent fungal diseases. Regular care will ensure healthy growth and vibrant blooms.
How do I propagate Vinca?
Vinca can be easily propagated through stem cuttings. Take 4-6 inch stem cuttings from healthy plants. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in moist, well-draining potting mix. Cover with a plastic bag or humidity dome to maintain moisture. Keep in a warm, bright location, but avoid direct sunlight. Roots should develop in 2-4 weeks. Once rooted, transplant into individual pots. Vinca is not typically propagated by division or keiki. Stem cuttings are the most reliable method for home propagation. Regular watering and humidity are crucial for successful rooting.
