Goldfish Plant vs Lisianthus 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.
Lisianthus
Eustoma grandiflorum
Lisianthus is an herbaceous annual or short-lived perennial plant typically grown for its exquisite, rose-like flowers. It features smooth, gray-green leaves and upright stems that can reach varying heights depending on the cultivar. The flowers come in a wide array of colors, including white, pink, purple, blue, yellow, and bi-colors. Lisianthus is primarily an outdoor plant, often cultivated in gardens and used as cut flowers due to their long vase life. While it can be grown indoors, it requires very specific conditions to thrive and flower successfully.

❓ 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.
Lisianthus
What are the light requirements for Lisianthus?
Lisianthus thrives in bright, indirect light. Direct sunlight can scorch the leaves, especially during the hottest part of the day. An east-facing window is ideal, providing gentle morning sun. A west-facing window can work if you provide some afternoon shade. If using a south-facing window, place the plant a few feet away from the window or use a sheer curtain to filter the light. Insufficient light can result in leggy growth and reduced blooming. Rotate the plant regularly to ensure even light exposure on all sides. Artificial grow lights can supplement natural light, especially during winter months, providing 14-16 hours of light per day.
How do I care for Lisianthus?
Lisianthus requires well-draining soil and consistent moisture. Water when the top inch of soil feels dry, avoiding overwatering which can lead to root rot. Provide bright, indirect light for optimal growth and blooming. Fertilize every 2-4 weeks during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Deadhead spent flowers to encourage further blooming. Maintain a temperature between 60-75°F (15-24°C). Prune as needed to maintain shape and remove any dead or yellowing leaves. Ensure good air circulation to prevent fungal diseases. Repot annually in spring if needed, using a slightly larger pot. Protect from frost and extreme temperatures. Monitor for pests and treat promptly if necessary.
How do I propagate Lisianthus?
Lisianthus is most commonly propagated by seed, as other methods are challenging. To propagate by seed: sow seeds indoors 10-12 weeks before the last frost. Use a seed-starting mix and keep it consistently moist. Germination can be slow and uneven, taking up to three weeks. Provide bottom heat and bright, indirect light once seedlings emerge. Transplant seedlings into individual pots when they are large enough to handle. Keep the soil consistently moist and fertilize lightly. While division and stem cuttings are possible, they are not typically successful due to the plant’s delicate nature.
