Feather Grass vs Parrot's Feather Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Feather Grass
Stipa tenuissima
Stipa tenuissima, commonly known as Mexican Feather Grass, is a perennial bunchgrass prized for its delicate, airy appearance. It forms dense clumps of fine, thread-like green leaves that sway gracefully in the breeze. In summer, it produces feathery, silvery-green flower panicles that turn golden-tan as they mature. It is primarily an outdoor plant, grown for its ornamental value in gardens and landscapes, adding texture and movement. While visually appealing, it can become invasive in some regions.
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.

💧 Watering Needs
Feather Grass
Water deeply when the top inch of soil feels dry. Avoid overwatering, which can lead to root rot. Established plants are drought-tolerant but benefit from occasional watering during dry spells. Signs of underwatering include browning leaf tips and drooping. Overwatering can cause yellowing leaves and a mushy base.
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.

❓ Frequently Asked Questions — Comparing These Plants
Feather Grass
What are the light requirements for Feather Grass?
Feather Grass requires a minimum of six hours of direct sunlight daily to thrive and produce its characteristic feathery plumes. Insufficient light will result in weak, leggy growth and reduced flowering. When planting in a garden, choose a location that receives full sun throughout the day. For container-grown Feather Grass, place it in a sunny spot, such as a south-facing balcony or patio. Rotate the container occasionally to ensure even light exposure. Indoors, a sunny windowsill or a grow light can supplement natural light. Lack of light will cause the plumes to be less abundant and less vibrant.
How do I care for Feather Grass?
Feather Grass thrives in full sun and well-drained soil. Water deeply but infrequently, allowing the soil to dry out between waterings. Overwatering can lead to root rot. Fertilize sparingly in spring with a balanced fertilizer to promote healthy growth. Prune back dead foliage in late winter or early spring before new growth emerges. Provide good air circulation to prevent fungal diseases. In colder climates, protect the crown of the plant with mulch during winter. Divide clumps every few years to maintain vigor and prevent overcrowding. Monitor for pests such as aphids or spider mites and treat accordingly. Proper drainage is crucial for successful cultivation.
How do I propagate Feather Grass?
Feather Grass is most easily propagated by division. In early spring or late fall, carefully dig up a mature clump and divide it into smaller sections, ensuring each section has healthy roots and foliage. Replant the divisions in well-draining soil, spacing them appropriately. Water thoroughly after planting. Alternatively, you can collect seeds from the plumes and sow them in spring, although germination rates may vary. Stem cuttings and keiki propagation are not applicable to Feather Grass. Division is the most reliable method. Ensure the divisions are planted at the same depth as the original plant.
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.
How do I propagate Parrot's Feather?
Parrot’s Feather is easily propagated through cuttings. Simply cut a healthy stem section, about 4-6 inches long, and remove the lower leaves. You can propagate in water or directly in moist substrate.
