Alocasia macrorrhiza 'Black Stem' - frunze ginantice si tulpini negre

Alocasia macrorrhiza 'Black Stem' is a spectacular variety of Alocasia, especially appreciated for its intensely black-purple, almost black stems (petioles), which create a dramatic and elegant contrast with the large, glossy green leaves.

The leaves are large, sagittate (arrow-shaped), glossy, with well-defined veins. The plant has vigorous, upright growth, being one of the more robust varieties in the Alocasia genus.

Main features:

• Intensely black-purple stems (petioles) (main characteristic)
• Large, green, glossy, arrow-shaped leaves
• Dramatic and exotic appearance
• Vigorous growth
• Size: 1.2 – 2 m tall (in pot at maturity)

Care:

• Light: bright indirect light or bright semi-shade. Tolerates filtered direct light better than many other Alocasias.
• Temperature: warm. Optimal 20–28°C. Does not tolerate temperatures below 12–13°C for long periods.
• Watering: moderate to abundant during the growing season. Allow the substrate to partially dry out between waterings.

Uses: Alocasia macrorrhiza 'Black Stem' is a striking ornamental plant, suitable for large indoor spaces (living rooms, hallways) or for terraces and balconies protected during the warm season. Due to its size and the strong color contrast between stems and leaves, it creates a very powerful tropical effect.
