Seeds

• Less common due to the specific germination requirements and slower initial growth rates

Typical Issues

• Spider mites and mealybugs
• Root rot, may also occur in overly damp conditions

Treatment Recommendations

• Proper air circulation and using well-draining soil

• Enigmatic presence in African folklore and botanical literature

• Prized for its rarity and dramatic inflorescence
• Distinctive foliage and floral display provide a focal point in tropical or conservatory settings
