Stenospermation hilligii Sodiro

• Genus: Stenospermation
• Botanical Background: First described by the botanist Sodiro during early explorations of South American flora, the species has since been recognized for its unique morphological traits within the aroid family

• Geographical Range: Native to tropical rainforests in regions such as Ecuador
• Environment: Naturally thrives in warm, humid conditions with dappled light; typically grows in well-drained, organic-rich soils within forest understories

Leaves

• Large, glossy, and heart-shaped
• Elliptical leaves with pronounced venation
• texture and coloration contribute to its ornamental appeal

Inflorescence (Spadix & Spathe)

• Modest spathe and spadix that are generally pale in tone
• Structure supports specialized pollinators in its native habitat

Growth Habit

• Primarily terrestrial
• Developing from a rhizomatous base that supports its steady growth in shaded, forest floor environments

Light Requirements

• Bbest in bright, indirect light

Watering & Humidity

• Requires regular watering while allowing the top layer of soil to dry slightly between sessions
• High humidity is beneficial for optimal growth

Soil & Potting Mix

• A Prefers a well-draining, organically rich potting mix
• Containers should facilitate proper drainage to prevent root rot

Temperature & Fertilizer

• Maintains health in moderate to warm temperatures
• Balanced, diluted fertilizer during the growing season supports steady development

Division

• Propagation is most effectively achieved through division of the rhizome

Stem Cuttings (if applicable)

• No established cutting method

Seeds

• Seed propagation is possible, it is less common due to the longer period required for growth from seed

Typical Issues

• Spider mites and mealybugs
• Overwatering may lead to root rot, so proper drainage is essential

Treatment Recommendations

• Insecticidal soap or organic alternatives and maintain good air circulation to minimize fungal issues.

• The unusual leaf shape and modest yet distinctive inflorescence

• Ornamental foliage and ease of care make it a sought-after specimen

Wild Population Status

• Limited data on its conservation status habitat loss in tropical regions highlights the need for sustainable cultivation practices

Market Availability

• Moderately available among specialty plant collectors and may be considered rare in mainstream markets
