Parrot's Feather vs Yarrow Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Parrot's Feather
Myriophyllum aquaticum
Parrot's Feather is an aquatic perennial plant characterized by its feathery, bright green leaves that emerge both above and below the water surface. Submerged leaves are typically reddish. It spreads rapidly through rhizomes, forming dense mats. While sometimes grown in aquariums or water gardens for its ornamental value and ability to oxygenate water, it's primarily an outdoor plant. It is considered an invasive species in many regions due to its aggressive growth and ability to outcompete native vegetation. Its emergent stems can reach up to a foot above the water.
Yarrow
Achillea millefolium
Achillea millefolium, commonly known as Yarrow, is a herbaceous perennial characterized by its feathery, fern-like leaves and clusters of small, daisy-like flowers. Typically grown outdoors, it forms a spreading mat through rhizomes. The flowers, which bloom in summer, are usually white but can also be yellow, pink, or red in cultivated varieties. Yarrow is valued for its medicinal properties, drought tolerance, and ability to attract pollinators. It's primarily an outdoor plant and faces challenges when grown indoors due to its high light requirements and spreading nature.

💧 Watering Needs
Parrot's Feather
Requires consistently moist to wet conditions. If grown in a container, ensure the soil is always saturated. For outdoor ponds or water gardens, it naturally thrives in water. Overwatering is not a concern, but allowing the soil to dry out will cause the plant to suffer. Signs of underwatering include wilting and browning of leaves.
Yarrow
Water deeply when the top inch of soil is dry. Avoid overwatering, as yarrow is susceptible to root rot. Overwatering signs include yellowing leaves and a musty smell. Underwatering signs include wilting and crispy leaves.

❓ Frequently Asked Questions — Comparing These Plants
Parrot's Feather
What are the light requirements for Parrot's Feather?
Parrot’s Feather requires ample light to flourish. Ideally, it should receive at least 6 hours of direct sunlight per day, or bright indirect light. Insufficient light can lead to leggy growth and reduced vibrant color. When growing in aquariums, use full-spectrum LED lighting specifically designed for aquatic plants. Position the plant where it receives the most light, but be mindful of potential algae growth caused by excessive light. Adjust light intensity and duration based on the plant’s response. For outdoor ponds, ensure the plant is not overly shaded.
How do I care for Parrot's Feather?
Parrot’s Feather thrives in full sun to partial shade. Ensure at least 6 hours of sunlight daily for optimal growth. Maintain water temperatures between 60-80°F (15-27°C). Water should be clean and well-oxygenated. Regularly prune to control growth and prevent overcrowding. Fertilize with a liquid aquatic plant fertilizer every 2-4 weeks during the growing season (spring and summer). Monitor for pests like aphids and snails. If growing in a container, use a nutrient-rich aquatic soil. For submerged growth, provide sufficient light and carbon dioxide. Change the water regularly to prevent algae buildup. Good water circulation is crucial.
