Dendrobium polyanthum

The Many-Flowered Orchid: A Cascading Beauty

Dendrobium polyanthum is a truly captivating orchid species that hails from the Himalayas and Southeast Asia. This exquisite epiphyte is admired for its cascading sprays of fragrant flowers and its graceful growth habit, making it a prized addition to any orchid collection.

Distinctive Features

• Pseudobulbs: Slender, elongated pseudobulbs that are typically 20-40cm long (approximately 8-16 inches). The pseudobulbs store water and nutrients, enabling the orchid to thrive in its natural epiphytic environment.
• Flowers: Produces a profusion of delicate, fragrant flowers that are typically white or cream-coloured with a yellow or orange lip. The flowers are arranged in cascading sprays that can reach up to 30cm in length (approximately 12 inches).
• Growth Habit: This Dendrobium has a pendant growth habit, meaning its pseudobulbs and flower sprays gracefully hang downwards. It thrives when grown in a hanging basket or mounted on a piece of bark or cork.

Care Tips

• Light: Bright, indirect light is best. Avoid harsh direct sunlight, which can scorch the leaves.
• Water: Water the orchid thoroughly when the potting mix approaches dryness. Allow excess water to drain away completely. Reduce watering during the winter months when the plant is not actively growing.
• Humidity: This Dendrobium appreciates moderate to high humidity. You can increase humidity by using a humidifier, placing the plant on a pebble tray filled with water, or misting the leaves regularly.
• Temperature: Maintain intermediate to warm temperatures between 18-29°C (65-85°F) for optimal growth.
• Fertiliser: Use a balanced orchid fertiliser at half strength every two weeks during the growing season (spring and summer).
• Repotting: Repot every 2-3 years as needed, using a well-draining orchid potting mix. Choose a pot that is only slightly larger than the previous one.

Additional Notes

• Dendrobium polyanthum is a deciduous orchid, meaning it will lose its leaves during the winter months. This is a natural part of its growth cycle.
• This orchid can be propagated through division of the pseudobulbs.
• With proper care, your Dendrobium polyanthum will reward you with its exquisite beauty and delightful fragrance for many years to come.
