This elephant's ear on a stem lets you know if it's thirsty! The leaves of the Alocasia will then start to droop That's how you know when the elephant's ear plant needs more water. Unlike the other species, this Cucullata has a stem. This jungle plant needs high humidity. Always keep the soil moist, without letting the plant stand in water. Spray the leaves at least once per week. This prevents the leaf edges from drying out. The Alocasia prefers moderate sunlight and so it should be placed in partial shade. The air-purifying plant grows towards the light. Turn the Alocasia occasionally so it continues to grow straight upwards.
