Goldfish Plant vs Monkey Grass Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Goldfish Plant
Nematanthus gregarius
The Goldfish Plant (Nematanthus gregarius) is an epiphytic shrub known for its unique flowers that resemble small goldfish. It features glossy, dark green, oval-shaped leaves and produces vibrant orange-red flowers from spring to fall. While it can be grown indoors, it requires specific conditions to thrive and flower reliably. It's a popular choice for hanging baskets due to its trailing growth habit. People grow it for its unusual and attractive flowers, adding a touch of whimsy to indoor spaces.
Monkey Grass
Liriope muscari
Liriope muscari, commonly known as lilyturf or monkey grass, is a grass-like perennial often used as a ground cover or border plant. It features clumps of arching, strap-like, dark green leaves. While it resembles grass, it's not a true grass. It produces spikes of small, lavender to purple flowers in late summer, followed by blackish berries. Primarily an outdoor plant, it's valued for its low maintenance, drought tolerance, and ability to suppress weeds. It's rarely grown indoors due to its need for bright light and outdoor conditions.

- Water thoroughly when the top inch of soil feels dry.
- Fertilize every 2-4 weeks during the growing season with a balanced liquid fertilizer.
- Prune after flowering to promote bushier growth.
Monkey Grass Care Tips
Liriope muscari is primarily an outdoor plant. Indoor cultivation is challenging due to its high light requirements and need for well-draining soil. It can be aggressive, spreading via rhizomes. Toxicity to pets is a significant concern.
- Plant in well-draining soil to prevent root rot.
- Water deeply but infrequently, allowing the soil to dry slightly between waterings.
- Fertilize in spring with a slow-release fertilizer.
- Divide clumps every few years to control spread and rejuvenate the plant.

❓ Frequently Asked Questions — Comparing These Plants
Goldfish Plant
What are the light requirements for Goldfish Plant?
Goldfish Plants require bright, indirect light to thrive and produce their signature blooms. East- or west-facing windows are ideal, providing ample light without the harsh intensity of direct sunlight. Avoid placing the plant in direct south-facing windows, especially during the hottest part of the day, as this can cause leaf burn. If natural light is insufficient, supplement with a grow light. Insufficient light can result in leggy growth, fewer blooms, and pale leaves. Rotate the plant regularly to ensure even light exposure on all sides. A general rule is if you need a lamp to comfortably read in the spot the plant is in, the plant likely needs more light.
How do I care for Goldfish Plant?
Goldfish Plants thrive in bright, indirect light; 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 high humidity levels, ideally between 50-70%, using a humidifier or pebble tray. Fertilize every 2-4 weeks during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength to encourage blooming. Prune regularly to maintain shape and encourage bushier growth. Repot every 1-2 years in spring, using a well-draining potting mix. Provide temperatures between 65-75°F (18-24°C). Protect from drafts and sudden temperature changes. Watch for pests like aphids or mealybugs, and treat promptly if detected. During the dormant winter months, reduce watering and fertilization.
How do I propagate Goldfish Plant?
Goldfish Plants can be easily propagated through stem cuttings. Take a 4-6 inch stem cutting from a healthy plant. 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 or humidity dome to maintain high humidity. Place in bright, indirect light. Roots should develop in 4-6 weeks. Once rooted, transplant into a larger pot. Division is possible when repotting mature plants. Keiki formation is not common in Goldfish Plants. Ensure the humidity levels are high for successful propagation.
Monkey Grass
What are the light requirements for Monkey Grass?
Monkey Grass thrives in bright, indirect light. While it can tolerate some shade, too little light can lead to leggy growth and reduced vibrancy. Avoid direct sunlight, especially during the hottest parts of the day, as it can scorch the leaves. East-facing windows are ideal, providing gentle morning light. North-facing windows can also work if the light is sufficient. If you notice the leaves fading or stretching towards the light source, move the plant to a brighter location. Consider using grow lights if natural light is insufficient, especially during winter months. Rotate the plant regularly to ensure even light exposure on all sides.
How do I care for Monkey Grass?
Monkey Grass is relatively easy to care for. Provide bright, indirect light for optimal growth. Water regularly, keeping the soil consistently moist but not waterlogged. Ensure good drainage to prevent root rot. Fertilize lightly during the growing season (spring and summer) with a balanced liquid fertilizer. Prune away any dead or damaged foliage to maintain its appearance and encourage new growth. Monkey Grass prefers temperatures between 60-75°F (15-24°C) and appreciates high humidity. Mist the foliage regularly or use a humidifier to increase humidity levels, especially in dry environments. Repot every 2-3 years as needed, using a well-draining potting mix.
How do I propagate Monkey Grass?
Monkey Grass can be propagated through division, stem cuttings, and air layering.
