Alocasia Purple Sword
Botanical Name: Alocasia lauterbachiana 'Purple Sword'
Common Name(s): Purple Sword Alocasia, Upright Elephant Ear
The Alocasia Purple Sword is an eye-catching and elegant houseplant known for its striking, sword-like foliage. Native to the tropical rainforests of Southeast Asia, this Alocasia variety features long, narrow, and dramatically upright leaves with deeply serrated edges. The foliage displays a rich, deep green on the top surface, contrasted by vivid purple undersides, giving the plant its signature "Purple Sword" look. The glossy finish and bold leaf shape make this plant a standout piece in any indoor garden or décor setting.
Though its appearance is bold and exotic, the Alocasia Purple Sword has care needs similar to other Alocasias. It thrives in bright, indirect light and should be shielded from direct sunlight, which can cause the leaf edges to crisp or burn. This plant prefers warm, humid environments and does best in temperatures between 65-80°F (18-27°C). Maintaining high humidity is key to its health so consider using a humidifier or humidity tray to provide consistent moisture in the air, especially in drier seasons .
When it comes to watering, the Alocasia Purple Sword appreciates slightly moist soil but is sensitive to overwatering. Allow the top inch of the soil to dry out before watering again. Using a well-draining soil mix helps prevent root rot and ensures good airflow around the roots. It's generally better to underwater than to overwater this plant, as excess moisture can lead to fungal issues or root damage. Always empty saucers or trays under the pot to avoid water accumulation.
Note: Like other Alocasia species, the Purple Sword is toxic if ingested by pets or humans. Keep it out of reach of children and animals to ensure their safety.
