Alocasia Purple Sword (4")

Alocasia Purple Sword

Latin Name
Alocasia lauterbachiana

Care Difficulty
Moderate. Best suited for growers who can provide consistent warmth, humidity, and watering.

Light Requirements
Bright, indirect light. A few hours of gentle morning sun is beneficial, but avoid harsh afternoon sunlight, which can scorch the foliage.

Water Requirements
Keep the soil lightly moist, allowing the top 1 to 2 inches to dry between waterings. Water thoroughly, but never let the plant sit in standing water. Reduce watering during the winter months when growth slows.

Humidity
Prefers high humidity (60 to 80%). While it will tolerate average household humidity, higher humidity helps prevent brown leaf edges and promotes healthy growth.

Pet Safety
Not pet safe. Contains calcium oxalate crystals and is toxic if chewed by cats, dogs, or people. Keep out of reach of children and pets.

Growth Speed
Moderate to fast. Produces new leaves regularly during the growing season under ideal conditions.

Expected Mature Size

• Height: 3 to 4 feet
• Width: 2 to 3 feet

Pot Size
Repot every 2 to 3 years or when roots become crowded. Use a chunky, well-draining aroid potting mix and a container with drainage holes.

Where it Grows Best
Indoors in bright, indirect light with temperatures between 65 and 85°F (18 to 29°C). It thrives in warm, humid rooms and makes an excellent statement plant.

Common Mistakes

• Using dense potting soil that holds too much moisture.

Frequently Asked Questions

Why is it called Purple Sword?
Its long, narrow, upright leaves resemble swords, while the undersides display a rich burgundy to purple colour that creates striking contrast.

Can it go dormant?
Yes. Like many Alocasias, it may slow down or lose a few leaves during winter. Reduce watering during dormancy and resume regular care when new growth appears.

Why are my leaf edges turning brown?
Brown edges are usually caused by low humidity, inconsistent watering, or mineral buildup from tap water. Higher humidity and consistent watering help prevent this.

How often should I fertilize it?
Feed every 2 to 4 weeks during spring and summer with a balanced water-soluble houseplant fertilizer at half strength. Stop fertilizing during the winter months.

Can I propagate Alocasia Purple Sword?
Yes. It is typically propagated by dividing offsets or corms when repotting.

How do I keep the leaves looking their best?
Wipe the leaves occasionally with a soft, damp cloth to remove dust. This helps the plant absorb more light and keeps the dramatic foliage looking vibrant.
