Stenospermation archeri K.Krause

• Genus: Stenospermation
• Botanical Background: The species was first described by botanist K.Krause in the early 20th century. Its discovery contributed to expanding the understanding of the diverse Aroid family, particularly within tropical regions.

• Geographical Range: Native to the tropical regions of New Guinea
• Environment: Thrives in humid, shaded environments with consistent moisture; prefers acidic, well-draining soil types found in its native habitat.

Leaves

• Large, heart-shaped
•  Glossy green surface
• Leaves can grow up to 40 cm long and 25 cm wide, often with a prominent central vein

Inflorescence (Spadix & Spathe)

• Slender, upright spadix, often greenish or pale yellow
• Spathe is relatively short compared to the spadix and has a unique spiral appearance
• Pollination is generally carried out by insects attracted to the scent released from the inflorescence

Growth Habit

• Primarily terrestrial, growing in the soil, although it can sometimes be seen as an epiphyte in its native rainforest environment

Light Requirements

• Does best in bright, indirect light
• Direct sunlight can cause leaf burn, so filtered light is optimal.

Watering & Humidity

• Requires consistently moist soil, with regular watering to maintain high humidity
• Ideal humidity levels are between 60–80%

Soil & Potting Mix

• A well-draining, acidic potting mix rich in organic matter is ideal

Temperature & Fertilizer

• Prefers temperatures between 22°C and 28°C (72°F and 82°F)
• Fertilization should be light during the growing season, using a balanced, diluted liquid fertilizer once a month.

Division

• Most commonly propagated by division of the rhizome

Stem Cuttings (if applicable)

• No applicable method of cutting

Seeds

• Less common but can be done by collecting ripe seeds and sowing them in moist, well-drained conditions
• Germination can be slow.
  

Typical Issues

• Spider mites, mealybugs, and aphids
• Root rot may occur if the soil is kept too moist without proper drainage.

Treatment Recommendations

• Can be treated with insecticidal soap or neem oil
• Root rot can be prevented by ensuring good drainage and avoiding waterlogged soil
  

• Often sought after for its aesthetic appeal, particularly its unusual inflorescence and large, glossy leaves

• Prized for its striking foliage and inflorescence, making it a popular choice among Aroid collectors

Wild Population Status

• Not currently listed as endangered but its under threat from deforestation

Market Availability

• Relatively rare species in cultivation
• Mainly found in specialized Aroid collections or nurseries catering to enthusiasts
