Alocasia odora 'California' – Comprehensive Guide and Plant Care
Alocasia odora 'California', previously recognized as Alocasia gageana, is a striking tropical houseplant celebrated for its bold foliage and adaptability. This compact cultivar features broad, undulating leaves in a rich green hue with deeply sunken veins, creating a distinctive quilted texture. The large, paddle-shaped leaves, reaching up to 50 cm long and 38 cm wide, emerge from sturdy, upright petioles, providing an architectural presence.
Unlike Alocasia macrorrhizos, which has more prominent, raised lateral veins, Alocasia odora 'California' displays sunken veins, a smaller overall structure, and a more compact growth pattern. The glossy leaf surface enhances its vibrant appearance, making it a stunning centerpiece in any indoor collection.
Alocasia odora 'California' thrives in humid conditions and brings a lush, tropical atmosphere to interior spaces. Its thick cuticle helps reduce water loss, making it well-suited for fluctuating humidity. Unlike many Alocasia species that enter dormancy in cooler conditions, this plant remains semi-evergreen, tolerating dips in temperature down to 5°C.
A 2022 publication by Hay et al. reclassified Alocasia gageana as a synonym of Englerarum hypnosum. Further research clarified that the plant commonly cultivated as Alocasia gageana was actually a compact form of Alocasia odora, leading to its correct classification as Alocasia odora 'California'.
