Houseplant, crystal Anthurium

Family: Araceae

Crystal Anthurium is one of the eye-catching foliage species of Anthuriums whose heart-shaped leaves are velvety on the surface and the leaf color changes from bronzy-purple to deep-green with age. The foliage hangs vertically, displaying the prominent silvery veins. Under good light, the silvery veins reflect light like crystals and hence the name "Crystal Anthurium". The inflorescences are green spathes with a pale-green spandix. This plant flowers through out the year. It is native to the tropical regions of Panama to Peru where it grows as an epiphyte on trees. It may not be easy to grow under room conditions but with proper care it can last for many years.

How to Grow Crystal Anthurium

Light

Crystal Anthurium prefers bright indirect light. A curtain-filtered sunny window is perfect. Protect the plant from direct sunlight to avoid scorching of the leaves. Learn more on how to ensure your plant receives the correct light in this guide on understanding light for houseplants.

Water

Keep soil moist at all times for Crystal Anthurium during the growing season but reduce watering in the cold season to maintain the soil slightly moist. Avoid waterlogging as it may lead to the root-rot. Learn more on how to water houseplants.

Temperature

Average warmth with a minimum of 160C is ideal for Crystal Anthurium. Protect it from cold draughts. Find out more on temperature for houseplants.

Humidity

Crystal Anthurium requires high humidity. Raise humidity by more frequent misting or set the pot on a wet pebble tray. Clean the leaves by damp-wiping with a soft cloth to get rid of dust and avoid water drops on the leaves as it may cause fungal infection.

Feeding

Feed Cyrstal Anthurium every 3-4 weeks during the growing period with a balanced water-soluble fertilizer. Withhold feeding in the cold season as growth is minimal and feeding at this time can lead to fertilizer burn. Regularly flush out accumulated salts in the soil by running a stream of water through the soil until the water comes out through the drainage hole. Allow it to run for a few minutes and repeat several times. Find out more on feeding houseplants.

Repotting

Repot Crystal Anthurium every 2 years at the beginning of the growing season. Use a pot one-size larger and free-draining soil that is rich in organic matter. Ensure the pot has drainage holes to prevent waterlogging.

How to Prune Crystal Anthurium

Pruning Crystal Anthurium is easy. Remove yellow and dead leaves to maintain the plant neat and tidy. Cut the leaves at the base of the stem. Wayward leaves can also be removed to maintain the shape of the plant. Learn more on how to prune houseplants.

Crystal Anthurium can be propagated during the growing season from from splits. Divide the mother plant into several sections while ensuring each divison has some roots. Pot up the splits in moist soil in individual pots. Place the set up in a cool place and maintain the soil moist until new growth emerges. Ensure the crown of the plant is above the soil level to avoid rotting. Allow the plant to be well established before transplanting.
