Colocasia, commonly known as Elephant Ears or Taro, is a dramatic genus of tropical aroids renowned for their massive, heart-shaped leaves. Colocasia esculenta is the primary cultivated species, prized for its bold architectural foliage and edible tubers. These plants create instant tropical impact as houseplants and garden specimens.
Bright indirect light to partial shade. Direct sun can scorch leaves unless acclimated. Variegated types need more light to maintain coloration.
Keep soil consistently moist to wet. Colocasias thrive with constantly damp soil and tolerate brief standing water. Never allow to dry out completely.
Rich, loose, organic potting mix that retains moisture but drains well. Add peat moss, compost, and perlite. Ideal pH 5.5-6.5.
Warm tropical conditions: 70°F-85°F (21°C-29°C). Cannot tolerate below 55°F (13°C). Requires high humidity above 60%; use humidifier or pebble trays.
Heavy feeders. Apply balanced liquid fertilizer every 2 weeks during growing season. Use higher nitrogen formulas for lush foliage growth.
Remove dead or yellowing leaves at base. Divide crowded clumps every 2-3 years in spring. Clean dust from large leaves with damp cloth.
