Amorphophallus henryi N.E.Br.

• Genus: Amorphophallus
• Botanical Background: Described by N.E.Br., the species has attracted interest from early 20th-century botanists; its discovery and description reflect a period of extensive botanical exploration in Asia and contributed to our modern understanding of aroid diversity.

• Geographical Range: Native to selected regions of East Asia.
• Environment: Naturally grows in humid, well-drained forest soils with abundant organic matter; favors warm conditions with a defined rainy season, typical of its native habitat, which supports its seasonal growth cycle.

Leaves

• Large, palmate leaves with lobed edges
• Deep green hue
• Medium to deep green coloration

Inflorescence (Spadix & Spathe)

• Features a distinct spadix encircled by a broad spathe
• Spathe is often tinted in rich greens or purplish hues. showier species
• When in bloom, the inflorescence can emit a notable scent to attract specific pollinators

Growth Habit

• A terrestrial plant emerging from an underground tuber
• A dormant period interspersed with rapid vegetative growth

Light Requirements

• Bright, indirect light
• Mimicking the dappled light of a forest understory helps to maintain its vibrant foliage

Watering & Humidity

• Regular watering is recommended during the active growing season
• Maintaining high humidity without waterlogging the roots

Soil & Potting Mix

• A loose, well-draining potting mix rich in organic material is idea
• Balanced blend that replicates the forest floor conditions works best in container culture

Temperature & Fertilizer

• Maintain temperatures above 60°F (16°C)
• A balanced, water-soluble fertilizer applied every 4–6 weeks will support robust growth without overwhelming the plan

Division and Cuttings

• Most reliable propagation method is the division of the tuber during the dormant phase

Seeds

• Less common given the slow germination rate; when attempted, seeds require specific stratification and consistent moisture for successful sprouting

Typical Issues

• Spider mites and mealybugs
• Fungal issues like root rot if the soil is overly moist

Treatment Recommendations

• Insecticidal soap or neem oil
• Improve soil drainage to prevent fungal infections

• Notable for its infrequent yet dramatic flowering, making its blooming event highly anticipated among enthusiasts

• Prized for its unusual structure and rare appearances in bloom
• Impressive foliage and singular inflorescence render it an attractive specimen in both private collections and botanical gardens

Wild Population Status

• Can be sparse, prompting localized conservation efforts to monitor and protect its natural habitat

Market Availability

• Seldom found in mainstream horticulture due to its rarity and specialized growing requirement
• Available through specialist nurseries or botanical exchanges
