Amorphophallus hirtus N.E.Br.

• Genus: Amorphophallus
• Botanical Background: Described by the renowned botanist N.E. Brown, whose work contributed significantly to the classification of African aroids; species has since been studied for its unusual inflorescence structure.

• Geographical Range: Indigenous to tropical regions of Africa
• Environment: High-humidity areas with well-drained, organically rich soils; favors environments that experience consistent warmth along with seasonal rainfall.

Leaves

• Broad, basal leaves that may exhibit a lobed structure with a moderate texture
• Subtle hairiness, complementing the overall “hirtus” trait

Inflorescence (Spadix & Spathe)

• Moderately large spathe with hints of green and reddish hues, and a spadix that shows fine hair-like structures
• Odor is generally mild compared to other aroids

Growth Habit

• A terrestrial herb that grows from a tuber that may extend into a rhizome
• Allows the plant to persist through dormant periods

Light Requirements

• Bright, indirect light
• Direct sun may scorch its foliage

Watering & Humidity

• Best maintained with consistent watering to keep the soil evenly moist
• High humidity levels
• Occasional misting or placement near a humidity tray in drier climates

Soil & Potting Mix

• Best in a rich, well-draining potting mix enhanced with organic matter
• Containers should feature ample drainage to prevent waterlogging

Temperature & Fertilizer

• Ideal temperature ranges between 65°F and 80°F
• A balanced, diluted fertilizer applied during the growing season can help promote vigorous growth

Division and Cuttings

• Most common propagation method is through the division of its tubers during its dormant period, which allows for the sustainable production of new plants

Seeds

• Less frequently practiced due to the challenges of achieving consistent germination under controlled conditions

Typical Issues

• Spider mites and mealybugs
• Susceptible to fungal root rot if overwatered or if the potting medium retains too much moisture

Treatment Recommendations

• Insecticidal soaps are effective for pest management
• Ensuring proper drainage and adjusting watering routines are key to preventing fungal infections

• Named for its “hairy” spathe and inflorescence
• Captured the interest of botanists and collectors alike, with its unique morphology inspiring local folklore in its native regions

• Prized in specialized aroid collections. Its scarcity further enhances its appeal to serious horticultural enthusiasts

Wild Population Status

• Habitat loss in tropical regions may pose risks. Conservation measures are advised for sustainable management

Market Availability

• Considered rare in the horticultural trade, typically available through specialized collectors, botanical gardens, or niche nurseries
