Aralia vs Lemongrass Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Aralia
Aralia spinosa
Aralia spinosa, commonly known as Devil's Walking Stick, is a deciduous shrub or small tree typically reaching heights of 6-20 feet. It features a distinctive, sparsely branched habit with extremely large, bipinnately or tripinnately compound leaves, giving it a bold, architectural appearance. The stems are heavily armed with sharp spines, hence the name. It produces large panicles of small, white flowers in late summer, followed by dark purple berries. Primarily an outdoor plant, it is grown for its unique foliage and structural interest in gardens and naturalized areas. Attempting to grow it indoors is challenging due to its size and light requirements.
Lemongrass
Cymbopogon citratus
Lemongrass is a tall, perennial grass characterized by its fragrant, lemon-scented leaves and stalks. It typically grows in dense clumps, reaching heights of 3-5 feet outdoors. The plant is primarily grown for its culinary and medicinal uses, as well as its aromatic properties. While it can be grown indoors, it requires very bright light and consistent care to thrive. It is more commonly cultivated outdoors in warmer climates.

💡 Pro Tips For Comparing These Plants
Aralia Care Tips
Aralia spinosa is primarily an outdoor plant and is challenging to grow indoors due to its size, light requirements, and potential for aggressive spread via suckers. Indoor cultivation requires a very bright location, careful watering, and management of its growth habit. It's best suited for experienced gardeners.
- Provide well-draining soil to prevent root rot.
- Water deeply but infrequently, allowing the soil to dry slightly between waterings.
- Fertilize in spring and early summer with a balanced fertilizer.
- Prune regularly to control size and shape.
- Monitor for pests and diseases and treat promptly.
Lemongrass Care Tips
Lemongrass is relatively easy to grow outdoors in warm climates with ample sunlight. Indoor cultivation is challenging due to high light requirements. It needs regular watering, fertilization, and repotting due to its fast growth and rhizomatous nature. Toxicity to pets is a major concern.
- Provide at least 6 hours of direct sunlight daily.
- Water deeply when the top inch of soil is dry.
- Fertilize regularly during the growing season.
- Protect from frost in colder climates.
- Divide the plant every 1-2 years to prevent overcrowding.

❓ Frequently Asked Questions — Comparing These Plants
Aralia
What are the light requirements for Aralia?
Aralia thrives in bright, indirect light. Avoid direct sunlight, as it can burn the delicate leaves. An east-facing window is ideal, providing gentle morning light. If you only have south or west-facing windows, place the Aralia further away from the window or use sheer curtains to filter the light. Insufficient light can lead to leggy growth and leaf drop. Rotate the plant regularly to ensure even light exposure on all sides. During the darker winter months, consider supplementing with a grow light to maintain optimal growth. Monitor the plant’s leaves for signs of overexposure (scorching) or underexposure (yellowing).
How do I care for Aralia?
Aralia requires bright, indirect light to thrive. Avoid direct sunlight, which can scorch the leaves. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Maintain a consistent watering schedule, but avoid overwatering. Aralia prefers a humid environment; mist the plant regularly or place it on a pebble tray filled with water. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Prune regularly to maintain shape and encourage bushier growth. Repot every 1-2 years into a slightly larger pot with well-draining potting mix. Maintain a stable temperature between 65-75°F (18-24°C) and protect from drafts.
How do I propagate Aralia?
Aralia can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from a healthy stem. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix and keep it consistently moist. Cover with a plastic bag to increase humidity. Roots should develop in 4-6 weeks. For air layering, make a small cut on a stem and wrap it with moist sphagnum moss. Cover the moss with plastic wrap and secure it with tape. Once roots appear through the moss, cut the stem below the roots and pot it in soil. Provide bright, indirect light and consistent moisture.
Lemongrass
What are the light requirements for Lemongrass?
Lemongrass demands bright, indirect sunlight for optimal growth. Insufficient light can lead to leggy growth and reduced essential oil production, diminishing its characteristic aroma. A south- or east-facing window is ideal, providing ample light without direct scorching. If direct sunlight is unavoidable, filter it with a sheer curtain. Rotate the plant regularly to ensure even light exposure on all sides. If natural light is inadequate, supplement with a grow light for at least 6 hours per day. Monitor leaf color; pale or yellowing leaves may indicate too much direct sunlight, while elongated stems suggest insufficient light.
How do I care for Lemongrass?
Lemongrass thrives with bright, indirect sunlight, needing at least 6 hours daily. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Maintain a consistently moist soil, but avoid overwatering. A well-draining potting mix is crucial for healthy growth. Fertilize every 2-4 weeks during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Maintain humidity levels around 50-60% by misting regularly or using a humidifier. Prune regularly to encourage bushier growth and remove any dead or yellowing leaves. Repot annually in spring to provide fresh soil and more room for growth. Protect from frost, as Lemongrass is sensitive to cold temperatures. Ensure good air circulation to prevent fungal diseases.
How do I propagate Lemongrass?
Lemongrass can be easily propagated through division, stem cuttings, or air layering. For division, carefully separate the plant clump into smaller sections, ensuring each section has healthy roots. Replant each section in a separate pot with well-draining soil. For stem cuttings, take a healthy stem cutting about 4-6 inches long. Remove the lower leaves and place the cutting in water. Once roots develop, transplant it into soil. Air layering involves making a small cut on a stem, wrapping it with moist sphagnum moss, and covering it with plastic wrap. Once roots emerge through the moss, cut the stem below the roots and plant it in soil. Keep the soil consistently moist and provide bright, indirect light for successful propagation.
