Feverfew vs Mare's Tail Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Feverfew
Tanacetum parthenium
Feverfew is a short-lived perennial plant typically grown as an annual, reaching heights of 18-24 inches. It features aromatic, fern-like foliage and daisy-like flowers with white petals surrounding a yellow disc. While historically cultivated for medicinal purposes, particularly for migraine relief, it is also grown ornamentally for its charming appearance in gardens. It is primarily an outdoor plant and can be challenging to maintain indoors due to its high light requirements and susceptibility to pests in enclosed environments.
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
Feverfew
What are the light requirements for Feverfew?
Feverfew requires ample sunlight to thrive and produce abundant blooms. Ideally, it needs at least six hours of direct sunlight per day. A south-facing window or a sunny spot in the garden is perfect. If grown indoors, place it near the brightest window possible. Insufficient light can lead to leggy growth, reduced flowering, and pale foliage. If natural light is limited, supplement with artificial grow lights. Rotate the plant regularly to ensure even light exposure on all sides. During the peak of summer, some afternoon shade may be beneficial to prevent scorching, especially in hotter climates. Monitor the plant for signs of light stress, such as bleached leaves or stunted growth, and adjust its location accordingly. Remember that the intensity of sunlight varies throughout the year, so you may need to adjust the plant’s position to maximize light exposure during the darker months.
How do I care for Feverfew?
Feverfew thrives in well-draining soil and prefers a sunny location with at least six hours of direct sunlight daily. Water regularly, allowing the soil to dry slightly between waterings. Avoid overwatering, as this can lead to root rot. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer to encourage abundant blooms. Deadhead spent flowers to promote continuous flowering. Prune back the plant in late fall or early spring to maintain its shape and encourage bushier growth. Feverfew is generally pest and disease-resistant, but monitor for aphids or spider mites and treat accordingly. Provide good air circulation to prevent fungal diseases. In colder climates, Feverfew may benefit from winter protection, such as mulching around the base of the plant. Ensure the soil pH is slightly acidic to neutral (6.0-7.0). Consider growing Feverfew in containers for easier control of growing conditions. Regular monitoring and timely intervention will keep your Feverfew healthy and vibrant.
How do I propagate Feverfew?
Feverfew can be easily propagated through division, stem cuttings, and seeds. For division, carefully dig up an established plant in spring or fall and separate the root ball into smaller clumps, ensuring each clump has healthy roots and foliage. Replant the divisions in well-draining soil. For stem cuttings, take 4-6 inch cuttings from healthy stems in spring or summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in moist potting mix and keep them humid until rooted. Seeds can be sown directly in the garden in spring or fall, or started indoors 6-8 weeks before the last frost. Maintain consistent moisture and provide adequate light. Keiki propagation is not applicable to Feverfew.
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.
