Key Characteristics of Radermachera

1. Appearance:

   • Features delicate, feathery leaves that are deep green and glossy.
   • The foliage grows in clusters, giving the plant a bushy, elegant look.
   • In its natural habitat, the plant can produce trumpet-shaped flowers, usually white or pale yellow, with a pleasant fragrance.

2. Size:

   • Indoors, it can grow between 2 to 6 feet (0.6–1.8 meters) tall, depending on pot size and care.
   • Outdoors, in suitable climates, it can reach heights of 30 feet (9 meters) or more.

3. Growth Habit:

Growing Conditions

1. Light:

   • Prefers bright, indirect light.
   • Can tolerate some direct sunlight, but avoid prolonged exposure to harsh midday sun.
   • Low light may cause the plant to become leggy or lose its vibrant foliage.

2. Soil:

   • Requires well-draining soil, such as a standard potting mix with added perlite or sand.
   • Ensure the pot has adequate drainage holes.

3. Watering:

   • Keep the soil consistently moist but not waterlogged.
   • Allow the top inch of soil to dry out slightly between waterings.
   • Overwatering can lead to root rot, while underwatering may cause leaf drop.

4. Temperature:

   • Thrives in temperatures between 60°F and 80°F (15°C to 27°C).
   • Sensitive to cold drafts and temperatures below 50°F (10°C).
