Parrot's Feather vs Speedwell 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.
Speedwell
Veronica spp.
Speedwell encompasses a diverse genus of flowering plants, primarily herbaceous perennials, though some are annuals or shrubs. They exhibit a range of growth habits, from creeping groundcovers to upright forms. The flowers are typically small and blue, but can also be pink, white, or purple, arranged in spikes or racemes. Speedwell is primarily grown outdoors in gardens and meadows for its attractive flowers and ability to attract pollinators. While some species are relatively adaptable, they generally require specific outdoor conditions that are difficult to replicate indoors.

💧 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.
Speedwell
Water thoroughly when the top inch of soil feels dry. Avoid overwatering, which can lead to root rot. Speedwell prefers consistently moist, but not soggy, soil. In hotter weather, more frequent watering may be necessary. Reduce watering during dormancy.

❓ 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.
Speedwell
What are the light requirements for Speedwell?
Speedwell flourishes in full sun, requiring at least six hours of direct sunlight each day for optimal growth and abundant blooming. While it can tolerate some partial shade, especially in hotter climates, insufficient light can lead to leggy growth and reduced flowering. When planting Speedwell, choose a location that receives ample sunlight throughout the day. If growing indoors, place the plant near a sunny window, ideally facing south or east. Rotate the plant regularly to ensure even light exposure on all sides. In areas with intense afternoon sun, providing some light shade during the hottest part of the day can prevent leaf scorch.
How do I care for Speedwell?
Speedwell thrives in well-draining soil and requires regular watering, especially during dry periods. Aim to keep the soil consistently moist, but avoid overwatering, which can lead to root rot. Provide Speedwell with at least six hours of sunlight daily for optimal blooming. In hotter climates, some afternoon shade can be beneficial. Fertilize your Speedwell every 4-6 weeks during the growing season with a balanced fertilizer to promote healthy growth and abundant blooms. Deadhead spent flowers regularly to encourage continuous flowering. Prune back the plant in late fall or early spring to maintain its shape and promote bushier growth. Protect Speedwell from extreme cold and frost in colder climates. Monitor for pests and diseases, and treat promptly if necessary.
How do I propagate Speedwell?
Speedwell can be propagated through division, stem cuttings, and seeds.
