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

Cape Marigold

Water regularly, especially during dry periods, allowing the soil to dry slightly between waterings. Avoid overwatering, which can lead to root rot. Signs of underwatering include wilting and dry, crispy leaves. Overwatering can cause yellowing leaves and a mushy stem 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.

💡 Pro Tips For Comparing These Plants

Cape Marigold Care Tips

Cape Marigold is an outdoor plant unsuited to indoor conditions. It requires full sun and well-drained soil. It is relatively easy to grow outdoors in suitable climates, but attempting to grow it indoors will be very challenging due to its high light requirements and need for good air circulation. It is also toxic to pets.

  • Sow seeds directly into the garden after the last frost.
  • Choose a location with full sun and well-drained soil.
  • Water regularly, especially during dry periods.
  • Deadhead spent flowers to encourage continued blooming.
  • Fertilize every 4-6 weeks during the growing season.
❄️ Winter: As an annual, the plant will die back in winter. Allow the plant to set seed or collect seeds for the following year.
☀️ Summer: Provide regular watering, especially during dry periods. Deadhead spent flowers to encourage continued blooming. Fertilize every 4-6 weeks during the growing season.

Parrot's Feather Care Tips

Parrot's Feather is primarily an outdoor aquatic plant and requires very specific conditions to thrive indoors. It needs intense light, constant moisture, and high humidity. It is an aggressive spreader, so containment is crucial. Indoor growth is challenging and often unsuccessful.

  • Provide ample sunlight to prevent leggy growth.
  • Regularly prune to control its spread and maintain shape.
  • Monitor water quality and adjust as needed.
  • Fertilize during the growing season to promote healthy growth.
  • Consider using a floating barrier to contain its spread in larger ponds.
❄️ Winter: Growth slows significantly in winter. Reduce fertilization. In colder climates, protect from freezing temperatures by moving to a sheltered location or providing insulation.
☀️ Summer: Ensure adequate water levels and sunlight. Monitor for algae growth and address as needed. Prune regularly to control spread.

❓ Frequently Asked Questions — Comparing These Plants

Cape Marigold

What are the light requirements for Cape Marigold?

Cape Marigolds thrive in full sun, requiring at least 6 hours of direct sunlight each day to produce abundant blooms. Insufficient light will result in fewer flowers and leggy growth. When grown indoors, place them near a south-facing window where they can receive the most intense sunlight. If natural light is limited, supplement with grow lights to ensure adequate illumination.

How do I care for Cape Marigold?

Cape Marigolds need full sun, at least 6 hours daily, to bloom profusely. Plant in well-draining soil, either in the garden or in containers. Water regularly, allowing the soil to dry slightly between waterings; avoid overwatering. Fertilize monthly during the growing season with a balanced fertilizer diluted to half strength, or a fertilizer formulated for blooming plants. Deadhead spent flowers regularly to encourage more blooms.

How do I propagate Cape Marigold?

Cape Marigolds can be propagated through stem cuttings. Take a 4-6 inch cutting from a healthy stem, removing the lower leaves. Dip the cut end in rooting hormone and plant in well-draining potting mix. Keep the soil moist and provide bright, indirect light. Roots should develop in a few weeks.

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.
