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.

Plume Poppy

Repotting N/A (Outdoor plant)
Pruning Cut back spent flower stalks after blooming to encourage tidiness and prevent self-seeding. Remove any dead or damaged foliage.
Fertilizing Apply a balanced slow-release fertilizer in early spring. Avoid over-fertilizing, as this can promote excessive foliage growth at the expense of flowering.
Seasonal Care In spring, apply fertilizer and divide if necessary. In summer, ensure adequate watering. In fall, cut back spent flower stalks. In winter, the plant will go dormant.

💧 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.

Plume Poppy

Water deeply when the top inch of soil feels dry. Avoid overwatering, which can lead to root rot. During hot, dry periods, more frequent watering may be necessary. Reduce watering in the fall as the plant prepares for dormancy. Signs of underwatering include wilting leaves, while overwatering can cause yellowing and mushy stems.

❓ 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.

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.

Plume Poppy

What are the light requirements for Plume Poppy?

Plume Poppy thrives best in full sun, requiring at least six hours of direct sunlight per day. However, it can also tolerate partial shade, especially in hotter climates where afternoon sun can scorch the leaves. In shadier locations, the plant may produce fewer flowers and become leggy.

How do I care for Plume Poppy?

Plume Poppy thrives in full sun to partial shade, requiring at least 6 hours of sunlight daily for optimal blooming. Plant in well-drained soil amended with organic matter. Water regularly, especially during dry periods, keeping the soil consistently moist but not waterlogged. Fertilize in spring with a balanced fertilizer to promote healthy growth and abundant flowering.

How do I propagate Plume Poppy?

Plume Poppy can be propagated through division, root cuttings, or seeds. Division is best done in spring or fall. Carefully dig up an established clump and divide it into smaller sections, ensuring each section has roots and shoots. Replant immediately.
