Fairy Moss vs Parasol Tree Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Fairy Moss
Azolla filiculoides
Azolla filiculoides, commonly known as Fairy Moss, is a small, free-floating aquatic fern. It forms a dense mat on the surface of still or slow-moving water. The plant is characterized by its tiny, overlapping leaves, which give it a moss-like appearance. It's typically grown outdoors in ponds, water gardens, or rice paddies. People cultivate it for its nitrogen-fixing abilities (symbiotic relationship with cyanobacteria), ornamental value, and potential use as a green manure or animal feed. It is not naturally an indoor plant and requires very specific conditions to thrive indoors.
Parasol Tree
Heptapleurum actinophyllum (syn. Schefflera actinophylla)
The Parasol Tree, or Umbrella Tree, is a fast-growing evergreen tree or shrub known for its distinctive palmate leaves that resemble an umbrella. In its native habitat, it can reach heights of up to 50 feet. It features multiple leaflets radiating from a central point, creating a visually striking effect. While primarily an outdoor plant, it is sometimes grown indoors as a houseplant, though it requires significant space and bright light to thrive. People grow it for its lush, tropical appearance and architectural form.

💧 Watering Needs
Fairy Moss
Requires constantly moist conditions. It floats on water, so the surrounding water body needs to be maintained. Avoid letting the water dry out completely.
Parasol Tree
Water thoroughly when the top inch of soil feels dry. Allow excess water to drain away. Overwatering can lead to root rot, indicated by yellowing leaves and a musty smell. Underwatering results in drooping leaves and dry, crispy edges.

❓ Frequently Asked Questions — Comparing These Plants
Fairy Moss
What are the light requirements for Fairy Moss?
Fairy Moss requires bright, indirect light to flourish. Insufficient light will result in stunted growth and a loss of vibrant coloration. Place your Fairy Moss near a window that receives filtered sunlight, or use artificial lighting specifically designed for aquatic plants. LED grow lights are an excellent option, providing consistent and controlled light exposure.
How do I care for Fairy Moss?
Fairy Moss thrives in calm, nutrient-rich water. Provide bright, indirect light; direct sunlight can scorch the delicate fronds. Water temperature should be between 65-80°F (18-27°C). Maintain excellent water quality by performing regular water changes, especially if kept in a closed aquarium system.
How do I propagate Fairy Moss?
Fairy Moss is incredibly easy to propagate through division. Simply separate a portion of the existing colony and place it in a new container with suitable water conditions. The separated portion will quickly grow and expand, forming a new colony.
Parasol Tree
What are the light requirements for Parasol Tree?
Parasol Trees thrive in bright, indirect light. While they can tolerate lower light conditions, they will grow best and maintain their vibrant color with ample light exposure. Avoid placing the plant in direct sunlight, especially during the hottest part of the day, as this can scorch the leaves. An east-facing window is often ideal, providing gentle morning sun. A north-facing window may also work, but the plant might not grow as quickly. If you don’t have a suitable window, you can supplement with artificial grow lights. Rotate the plant regularly to ensure even light exposure on all sides. Insufficient light can lead to leggy growth and faded leaf color.
How do I care for Parasol Tree?
Provide your Parasol Tree with bright, indirect light; direct sunlight can scorch its leaves. Water thoroughly when the top inch of soil feels dry, ensuring proper drainage to prevent root rot. Maintain a stable temperature between 65-75°F (18-24°C) and avoid sudden temperature fluctuations. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Repot every 1-2 years, or when the plant becomes root-bound, using a well-draining potting mix. Prune regularly to maintain shape and encourage bushier growth. Wipe leaves with a damp cloth to remove dust and pests. Monitor for common pests like spider mites and mealybugs, treating promptly if detected. Provide adequate humidity, especially during dry winter months, by misting regularly or using a humidifier. Rotate the plant periodically to ensure even growth on all sides. Avoid overwatering, which is a common cause of problems.
How do I propagate Parasol Tree?
Parasol Trees 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 it in a well-draining potting mix. Keep the soil moist and provide warmth and humidity. Roots should develop in a few weeks. For air layering, make a small cut on a stem, wrap it with moist sphagnum moss, and cover it with plastic wrap. Secure the plastic wrap with tape. Once roots develop, cut the stem below the roots and pot the new plant. Spring and summer are the best times for propagation. Ensure the cutting or air layer receives bright, indirect light. Maintain stable conditions during the rooting process.
