Amorphophallus josefbogneri Hett.

• Genus: Amorphophallus
• Botanical Background: Described by Hett., this species was named in honor of Josef Bogner, a notable figure in aroid research and cultivation. Its discovery and subsequent documentation contribute to our understanding of the genus’s diversity and the evolutionary relationships within the Araceae family.

• Geographical Range: Native to select regions in tropical Southeast Asia
• Environment: Naturally grows under the dappled light of tropical forest understories; favors humid conditions, well-draining organic soils, and environments where seasonal rainfall supports robust, year-round growth.

Leaves

• Broad and deeply veined
• Exhibit a lush, dark green coloration with a textured surface

Inflorescence (Spadix & Spathe)

• Moderately sized spadix encircled by a contrasting spathe
• Structure is both unusual and attractive; it may emit a mild scent to attract specific pollinator

Growth Habit

• Typical of many aroids, marked by a seasonal cycle of dormancy followed by rapid leaf and inflorescence development

Light Requirements

• Bright, indirect light that mimics its natural dappled forest environment
• Avoid direct sunlight, which can scorch its foliag

Watering & Humidity

• Regular watering is essential, especially during active growth phases
• Appreciates high ambient humidity and consistent moisture without waterlogging the soil

Soil & Potting Mix

• A well-draining potting mix rich in organic matter is ideal
• Mix incorporating components such as peat, perlite, and compost closely replicates its natural habitat conditions

Temperature & Fertilizer

• Prefers warm temperatures within the range of 24-29°C (75-85°F)
• A balanced, diluted fertilizer applied every 4-6 weeks can support healthy development

Division and Cuttings

• Most common method of propagation is by dividing the corm
• Should be undertaken during the plant's dormant period, ensuring each division has a healthy portion of the corm and basal roots

Seeds

• Seeds require warm temperatures and prolonged exposure to high humidity to germinate reliably; less frequently practiced compared to division

Typical Issues

• Spider mites and mealybugs
• Occasional fungal infections such as root rot

Treatment Recommendations

• Implement integrated pest management techniques using both chemical treatments (such as insecticidal soap) and organic remedies
• Ensure the cultivation environment does not retain excess moisture to reduce fungal risks

• Holds cultural intrigue, particularly among aroid enthusiasts who appreciate its rarity and the homage paid to Josef Bogner
• Specialized pollination strategy and periodic blooming add to its botanical allure

• Prized for its unusual inflorescence and elegant foliage
• Limited availability and unique growth habit make it a coveted specimen for botanical gardens and private collections alike

Wild Population Status

• Due to habitat loss in tropical regions, the wild populations of this species may be vulnerable

Market Availability

• While it occasionally appears in specialty nurseries, its availability is limited to dedicated collectors and botanical institutions
