Biarum auraniticum Mouterde

• Genus: Biarum
• Botanical Background: First described by Mouterde, this species is part of a genus that has long intrigued botanists. Its study has contributed to a deeper understanding of araceae diversity and adaptation in challenging environments

• Geographical Range: Native to regions with Mediterranean climates
• Environment: Thrives in warm conditions with well-draining soils. The species prefers environments that experience moderate rainfall, high light intensity, and occasional periods of drought

Leaves

• Leaves are arrow-shaped
• Leathery texture
• Subtle variegation
• Attractive, structured appearance

Inflorescence (Spadix & Spathe)

• Inflorescence features a compact spadix enclosed by a vividly colored spathe
• Structure is adapted to attract specific pollinators
• Not known for a strong scent

Growth Habit

• Terrestrial species that develops a tuberous root system

Light Requirements

• Bright, indirect light
• Mimics the filtered sunlight of its natural rocky outcrops

Watering & Humidity

• Moderate watering is recommended
• Allow the soil to dry between waterings
• Maintain higher humidity

Soil & Potting Mix

• Well-draining, mineral-rich potting mix is ideal
• Using a terracotta container can help regulate moisture levels effectively

Temperature & Fertilizer

• Optimal temperatures range from 65°F to 80°F
• Balanced fertilizer during the growth phase supports healthy development without overfeeding

Division & Cutting

• Most common method of propagation is through tuber division during the plant’s dormant season, which allows for natural clump formation

Seeds

• Period of stratification is generally needed to overcome dormancy and promote successful germination

Typical Issues

• Spider mites
• Root rot
• Overwatering may lead to root rot

Treatment Recommendations

• Neem oil
• Proper drainage minimizes the risk of fungal infections

• Attracted the attention of collectors due to its rarity and the striking appearance of its inflorescence

• Valued for its unusual leaf shape and the dramatic spathe display, this species is a coveted specimen in specialized aroid collections

Wild Population Status

• Habitat loss remains a concern for many rare aroids

• Monitoring initiatives are in place to better understand its wild populations
  

Market Availability

• Highly prized by aroid collectors and is often available only through specialist nurseries or exchange networks
