Epidendrum vs Mare's Tail Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Epidendrum
Epidendrum radicans
Epidendrum radicans is a terrestrial or epiphytic orchid characterized by its reed-like stems that can grow several feet long. It produces vibrant clusters of small, star-shaped flowers, typically orange, red, yellow, or pink, at the ends of its stems. This orchid is often grown for its long-lasting blooms and relatively easy care compared to other orchids. While it can be grown indoors, it thrives best outdoors in warm climates. People grow it for its colorful flowers and ability to attract pollinators.
Mare's Tail
Equisetum arvense
Equisetum arvense, commonly known as Mare's Tail or Horsetail, is a perennial plant characterized by its distinctive segmented stems that resemble a horse's tail. It grows from creeping rhizomes, allowing it to spread aggressively. The plant has two types of stems: fertile stems that produce spores and sterile stems that are green and photosynthetic. It is primarily an outdoor plant, thriving in moist environments. People grow it for its unique appearance, though its aggressive spreading habit can make it a challenging garden plant. It is not typically grown indoors due to its specific environmental needs and invasive nature.

❓ Frequently Asked Questions — Comparing These Plants
Epidendrum
What are the light requirements for Epidendrum?
Epidendrums require bright, indirect light to thrive and produce abundant blooms. Insufficient light can lead to weak growth and a lack of flowering. An east- or west-facing window is generally ideal, providing ample light without direct, harsh sunlight that can scorch the leaves. If growing indoors, supplement natural light with a grow light if necessary, especially during the darker winter months. Signs of insufficient light include dark green leaves and leggy growth. Conversely, too much direct sunlight can cause the leaves to turn yellow or brown. Rotate your Epidendrum regularly to ensure even light exposure on all sides. Adjust the plant’s position relative to the window to optimize light levels throughout the year.
How do I care for Epidendrum?
Epidendrums thrive in bright, indirect light; an east- or west-facing window is ideal. Water thoroughly when the potting mix is almost dry, allowing excess water to drain away. Avoid letting the plant sit in standing water to prevent root rot. Fertilize regularly during the growing season (spring and summer) with a balanced orchid fertilizer diluted to half strength, every 2-4 weeks. Reduce or stop fertilizing during the dormant season (fall and winter). Maintain moderate humidity levels, around 50-70%. Repot every 1-2 years using a well-draining orchid mix. Provide good air circulation to prevent fungal diseases. Prune spent flower spikes to encourage new growth. Monitor for pests such as mealybugs and scale, and treat promptly with insecticidal soap or neem oil. Ensure adequate drainage and avoid overwatering, which are the most common causes of problems. Maintain consistent care for optimal blooming.
How do I propagate Epidendrum?
Epidendrums can be propagated through division, stem cuttings, or keikis (small plantlets that form on the stem).
Mare's Tail
What are the light requirements for Mare's Tail?
Mare’s Tail requires moderate to high lighting for optimal growth. Insufficient light can lead to leggy growth and a decline in the plant’s health. In aquariums, provide at least 8-10 hours of light per day using fluorescent or LED aquarium lights. If growing Mare’s Tail outdoors in a pond, ensure it receives several hours of direct sunlight each day, but avoid excessive exposure to intense midday sun, which can scorch the leaves. Adjust the lighting intensity and duration based on the plant’s response. Watch for signs of etiolation (stretching towards the light) and adjust lighting accordingly.
How do I care for Mare's Tail?
Mare’s Tail thrives in aquatic or semi-aquatic environments. For submerged growth, maintain a water temperature between 60-75°F (15-24°C). Provide moderate to high lighting to encourage healthy growth. Ensure the water is clean and well-oxygenated, performing regular water changes (25-50% weekly) to remove accumulated nitrates and maintain water quality. Fertilize sparingly with a liquid fertilizer specifically formulated for aquatic plants, following the manufacturer’s instructions. If grown in a semi-aquatic setup, keep the roots consistently moist. Trim any dead or decaying foliage to prevent the spread of disease. Monitor for algae growth and address as needed with appropriate algaecides or by manually removing the algae.
How do I propagate Mare's Tail?
Mare’s Tail is easily propagated through cuttings.
