Jerusalem Cherry vs Lyme Grass Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Jerusalem Cherry
Solanum pseudocapsicum
Solanum pseudocapsicum, commonly known as Jerusalem Cherry, is a small, shrubby perennial plant often grown as an annual. It features glossy, dark green leaves and produces small, white, star-shaped flowers followed by bright, round berries that ripen to orange or red. These berries are the plant's main ornamental feature. While visually appealing, all parts of the plant, especially the berries, are poisonous. It is primarily an outdoor plant, but is often sold as a temporary indoor decoration. It is grown for its colorful berries, which provide winter interest.
Lyme Grass
Leymus arenarius
Lyme grass (Leymus arenarius) is a cool-season perennial grass known for its striking blue-gray foliage. It typically grows in clumps, reaching heights of 1 to 3 feet. This grass is native to sandy coastal areas and is well-adapted to harsh conditions like salt spray and nutrient-poor soils. It spreads aggressively via rhizomes, forming dense colonies. While primarily an outdoor plant used for erosion control and ornamental purposes, some gardeners attempt to grow it in containers. Its aesthetic appeal lies in its unique color and texture, making it a popular choice for landscaping.

💡 Pro Tips For Comparing These Plants
Jerusalem Cherry Care Tips
Jerusalem Cherry is challenging to maintain indoors due to its high light requirements and susceptibility to pests. It needs bright light, consistent watering, and careful monitoring for pests. The toxicity of the plant makes it unsuitable for homes with pets or small children. It is best suited as a temporary indoor plant or grown outdoors in suitable climates.
- Provide at least 6 hours of direct sunlight daily for optimal berry production.
- Maintain consistent soil moisture, but avoid overwatering.
- Monitor regularly for pests and treat promptly.
- Increase humidity around the plant by misting or using a humidifier.
- Fertilize regularly during the growing season to support healthy growth and berry development.
Lyme Grass Care Tips
Lyme grass is primarily an outdoor plant that thrives in full sun and well-draining soil. Indoor cultivation is challenging due to its high light requirements and aggressive spreading habit. It needs excellent drainage to prevent root rot. Regular division is necessary to control its spread.
- Plant in well-draining soil to prevent root rot.
- Provide full sun for optimal color and growth.
- Divide clumps every few years to control spread.

❓ Frequently Asked Questions — Comparing These Plants
Jerusalem Cherry
What are the light requirements for Jerusalem Cherry?
Jerusalem Cherry thrives in bright, indirect light. Avoid direct sunlight, which can scorch the leaves and damage the plant. An east-facing window is ideal, providing gentle morning sun. A west-facing window can work, but monitor for leaf scorch during the hottest part of the afternoon. If you don’t have access to adequate natural light, consider using a grow light to supplement.
How do I care for Jerusalem Cherry?
Jerusalem Cherry requires bright, indirect light; direct sunlight can scorch the leaves. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Maintain a moderate humidity level, especially during the winter months when indoor air tends to be drier. Fertilize every 2-3 weeks during the growing season (spring and summer) with a balanced liquid fertilizer, diluted to half strength.
How do I propagate Jerusalem Cherry?
Jerusalem Cherry can be propagated by 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 moist. Cover with a plastic bag to create a humid environment. Place in bright, indirect light and wait for roots to develop, which usually takes several weeks.
Lyme Grass
What are the light requirements for Lyme Grass?
Lyme Grass requires ample sunlight to thrive. Aim for at least six hours of direct sunlight daily, especially for aquatic varieties. If grown indoors in a large container, position the plant near a south-facing window or supplement with artificial grow lights. Insufficient light can lead to leggy growth, pale foliage, and reduced vigor. When planting in a pond, consider the angle of the sun and choose a location where the grass will receive maximum sunlight exposure throughout the day. Partial shade is tolerated, particularly in hotter climates, but full sun yields the best results for vibrant color and robust growth. Monitoring light levels and adjusting the plant’s position accordingly is crucial for its health.
How do I care for Lyme Grass?
Lyme Grass thrives in full sun to partial shade, requiring at least 6 hours of direct sunlight for optimal growth. Water quality is paramount; use dechlorinated water or allow tap water to sit for 24 hours to dissipate chlorine. Maintain a water pH between 6.0 and 7.5. For aquatic Lyme Grass, ensure the crown of the plant is just above the water level. For semi-aquatic Lyme Grass, keep the soil consistently moist. Fertilize sparingly with a diluted aquatic plant fertilizer during the growing season (spring and summer). Avoid over-fertilizing, as this can lead to algae blooms. Prune away any dead or yellowing foliage to maintain its appearance and prevent disease. Regularly check for pests like aphids and treat accordingly.
How do I propagate Lyme Grass?
Lyme Grass is easily propagated through division or cuttings.
