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.

Queen of the Night

Selenicereus grandiflorus

Selenicereus grandiflorus, commonly known as Queen of the Night, is an epiphytic or lithophytic cactus characterized by its long, sprawling, and often climbing stems. These stems are typically green to grayish-green, ribbed, and adorned with small spines. It is primarily grown for its spectacular, large, fragrant, white flowers that bloom only at night and wither by dawn. The plant is naturally an outdoor plant, thriving in tropical and subtropical climates. While it can be grown indoors, providing the right conditions for flowering can be challenging.

💧 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.

Queen of the Night

Water thoroughly when the soil is dry to the touch, allowing excess water to drain away. Reduce watering frequency during the dormant winter months. Overwatering can lead to root rot, indicated by soft, mushy stems. Underwatering results in shriveled stems.

💡 Pro Tips For Comparing These Plants

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.

Queen of the Night Care Tips

Queen of the Night is challenging to grow indoors due to its high light requirements and need for a distinct dry period in winter to encourage flowering. It requires careful attention to watering and humidity. Flowering indoors is rare without very specific conditions.

  • Provide a trellis or support structure for the stems to climb.
  • Ensure excellent drainage to prevent root rot.
  • Mimic the plant's natural environment with a distinct wet/dry cycle.
  • Provide a cool, dry rest period in winter to encourage flowering.
  • Protect from extreme temperatures and drafts.
❄️ Winter: Reduce watering significantly during the winter months. Provide a cool, dry environment with temperatures around 10-15°C. Avoid fertilizing during this period. This dormancy period is crucial for encouraging flowering in the spring.
☀️ Summer: Increase watering frequency during the summer months, allowing the soil to dry out between waterings. Fertilize monthly with a balanced liquid fertilizer. Provide ample sunlight and protect from intense afternoon sun to prevent scorching.

⚠️ Common Problems & Solutions — Plant Care Comparison

❓ 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.

Queen of the Night

What are the light requirements for Queen of the Night?

Queen of the Night cacti thrive in bright, indirect light. Direct sunlight can scorch the stems, especially during the hottest part of the day. An east-facing window is ideal, providing morning sun, while a west-facing window with some shading can also work. If grown indoors, supplement with grow lights if natural light is insufficient.

How do I care for Queen of the Night?

Queen of the Night cacti require bright, indirect light, well-draining soil, and careful watering. Water thoroughly when the top inch of soil is dry during the growing season (spring and summer), but reduce watering significantly during the dormant period (fall and winter). Avoid overwatering, as this can lead to root rot.

How do I propagate Queen of the Night?

Queen of the Night can be propagated through offsets, seeds, or grafting. Offsets, which are small plantlets that grow from the base of the plant, can be carefully removed and potted in well-draining cactus mix. Allow the cut end to callous over for a few days before planting.
