Amorphophallus Atroviridis

The Dark Emerald Titan

What Is Amorphophallus atroviridis?

Amorphophallus atroviridis is a rare tropical plant known for its dramatic dark green foliage and unusual flowering structure. It belongs to the Amorphophallus genus, a group of tuber-growing plants native to Southeast Asia.

This plant grows from an underground tuber and produces a single large, umbrella-like leaf during its growing season. It is not an aquatic plant and should not be submerged. Instead, it thrives in warm, humid conditions with well-draining soil.

The name atroviridis means “dark green,” referring to the deep emerald color of its leaf. When mature, it may produce a unique flower structure (spathe and spadix), typical of the Amorphophallus family.

Bold and architectural, Amorphophallus atroviridis is ideal for collectors who appreciate unusual tropical plants with strong presence.

How It Grows

This plant grows from a round underground tuber. During the active season, it produces one tall stem topped with a wide, divided leaf that looks like a small tree canopy.

After its growing period, the plant may enter dormancy, where the leaf dies back and the tuber rests before the next cycle.

The Leaves

The leaf is large and deeply divided into many smaller leaflets.

• Color: deep emerald to dark green

• Surface: smooth with a natural matte to soft sheen

• Shape: umbrella-like, spreading outward

The structure gives it a bold and tropical appearance.

Light Needs

Prefers bright, indirect light.

• Avoid strong direct sunlight

• Good light supports healthy leaf development

Too little light may result in weaker growth.

Water & Growing Conditions

• Keep soil moist during active growth

• Reduce watering during dormancy

• Use well-draining soil mix

• Prefers moderate to high humidity

• Ideal temperature: 22–30°C

Do not let the tuber sit in soggy soil.

Growing Environment

Best suited for:

• Indoor tropical plant collections

• Shaded outdoor tropical gardens (in warm climates)

• Greenhouse setups

Not suitable for aquariums or submerged environments.

Care Level

Medium care.

• Requires understanding of dormancy cycle

• Sensitive to overwatering

• Seasonal growth pattern

Handling Note

When the plant enters dormancy and the leaf dies back, do not panic. Reduce watering and allow the tuber to rest. With proper seasonal care, Amorphophallus atroviridis will return with strong, dramatic foliage in its next growth cycle.
