Citronella vs Euonymus 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.
Euonymus
Euonymus japonicus
Euonymus japonicus is a dense, evergreen shrub or small tree, typically grown outdoors for its attractive foliage and tolerance of various conditions. It features glossy, oval-shaped leaves that can be solid green or variegated with white or yellow margins. While it can be grown in containers, it is primarily an outdoor plant and may struggle indoors due to its need for bright light and specific humidity levels. People grow it for hedging, screening, or as an ornamental shrub in gardens and landscapes.

❓ 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.
Euonymus
What are the light requirements for Euonymus?
Euonymus indoor trees require bright, indirect light to thrive. Insufficient light can lead to leggy growth and faded foliage. A location near an east- or west-facing window is ideal, providing ample light without direct sun exposure. If placing near a south-facing window, use a sheer curtain to filter the harsh sunlight.
How do I care for Euonymus?
Euonymus thrives with bright, indirect light; avoid direct sunlight which can scorch the leaves. Water thoroughly when the top inch of soil feels dry, allowing excess water to drain away. Overwatering can lead to root rot, so ensure proper drainage. Maintain moderate humidity levels, especially during dry winter months, by misting the leaves regularly or using a humidifier. Fertilize every 2-4 weeks during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength.
How do I propagate Euonymus?
Euonymus can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from a healthy stem, removing the lower leaves. Dip the cut end in rooting hormone and plant in moist potting mix. Cover with a plastic bag to maintain humidity and place in bright, indirect light. Roots should develop in 4-8 weeks.
