Amorphophallus Manta

The Tropical Manta Canopy

What Is Amorphophallus ‘Manta’?

Amorphophallus ‘Manta’ is a striking tropical tuber plant known for its wide, dramatic leaf that spreads like the wings of a manta ray. It belongs to the Amorphophallus genus, a group of unusual plants native to Southeast Asia that grow from underground tubers.

This plant produces a single tall stem topped with a large, umbrella-shaped leaf during its active growing season. It is not an aquatic plant and should not be submerged. It grows best in warm temperatures, high humidity, and loose, well-draining soil.

Its bold structure and tropical presence make it popular among collectors who enjoy rare and architectural foliage plants.

How It Grows

The plant grows from a round underground tuber. During the growing season, one thick stem emerges and expands into a large, divided leaf canopy.

After its growth cycle, the leaf may die back naturally as the plant enters dormancy. The tuber rests before producing new growth in the next season.

The Leaves

The leaf is large and deeply divided.

• Color: medium to deep green

• Surface: smooth with a natural matte finish

• Shape: wide and spreading, similar to a manta ray’s wings

The overall form gives the plant a bold, tropical look.

Light Needs

Prefers bright, indirect light.

• Avoid strong direct sunlight

• Adequate light supports stronger stems and fuller leaf growth

Low light may result in weaker structure.

Water & Growing Conditions

• Keep soil moist during active growth

• Reduce watering during dormancy

• Use loose, well-draining soil mix

• Prefers moderate to high humidity

• Ideal temperature: 22–30°C

Never allow the tuber to sit in soggy soil.

Growing Environment

Best suited for:

• Indoor tropical collections

• Greenhouses

• Warm outdoor tropical gardens

Not suitable for aquariums or submerged setups.

Care Level

Medium care.

• Requires understanding of seasonal dormancy

• Sensitive to overwatering

• Moderate to fast growth in warm conditions

Handling Note

When the leaf naturally dies back, reduce watering and allow the tuber to rest. Do not discard the tuber during dormancy. With stable warmth and proper seasonal care, Amorphophallus ‘Manta’ will return with impressive, dramatic foliage.
