Mare's Tail vs Mexican Bush Sage Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
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.
Mexican Bush Sage
Salvia leucantha
Mexican Bush Sage is a perennial shrub prized for its velvety, often purple, flower spikes and aromatic foliage. It typically grows to a height of 3-4 feet and a similar spread. While primarily an outdoor plant, it's grown for its late-season blooms that attract pollinators like bees and hummingbirds. The plant's soft texture and vibrant colors make it a popular choice for gardens, borders, and containers. It is not naturally an indoor plant and requires very specific conditions to thrive indoors.

❓ Frequently Asked Questions — Comparing These Plants
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.
Mexican Bush Sage
What are the light requirements for Mexican Bush Sage?
Mexican Bush Sage requires at least 6-8 hours of direct sunlight each day to thrive and produce abundant blooms. Insufficient light can result in leggy growth, reduced flowering, and pale foliage. When grown indoors, place the plant near a south-facing window where it can receive maximum sunlight. If natural light is limited, supplement with grow lights. Rotate the plant regularly to ensure even light exposure on all sides. A lack of sunlight can also make the plant more susceptible to pests and diseases. During the winter months, when sunlight is less intense, consider moving the plant to a brighter location or increasing the duration of grow light exposure.
How do I care for Mexican Bush Sage?
Mexican Bush Sage thrives in full sun and well-draining soil. Water thoroughly when the top inch of soil is dry, but avoid overwatering, which can lead to root rot. Fertilize every 2-3 weeks during the growing season (spring and summer) with a balanced fertilizer, switching to a bloom-boosting formula as flowering approaches. Prune lightly in late winter or early spring to remove dead or damaged growth and encourage bushier growth. Provide support if the plant becomes leggy. Ensure good air circulation to prevent fungal diseases. Repot every 1-2 years as needed. Protect from frost in colder climates. Mulch around the base of the plant to retain moisture and suppress weeds. Monitor for pests like aphids and spider mites, and treat promptly if detected.
How do I propagate Mexican Bush Sage?
Mexican Bush Sage can be propagated through stem cuttings, division, or seeds. For stem cuttings, take 4-6 inch cuttings from new growth in spring or summer. 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. Roots should develop within a few weeks. For division, carefully dig up the plant in early spring and divide the root ball into smaller sections, ensuring each section has healthy roots and foliage. Replant the divisions in separate pots or in the garden. Seeds can be sown indoors in early spring. Keep the soil moist and warm until germination occurs. Transplant seedlings outdoors after the last frost.
