Colocasia gigantea (Leucocasia gigantea)
This species is among major survivors of the cold weathers Leucocasia (previously Colocasia) gigantea so it is being named ‘Survivor’. In rich, wet soils, it handily arrived at 8′ tall x 9′ wide.

2. By seeds
You can engender elephant ears by seed, sprinter, or by relocating. Elephant ears like to fill in soil that is reliably wet. Utilize a rich soil somewhere in the range of 5.5 and 7.0 pH.
Plant bulbs around 2 to 4 creeps under the dirt, more obscure assortments can be filled in the incomplete shade, yet the lighter cultivars fill best in full light. They need warm temperatures and incline toward high dampness. Keep in mind, while developing elephant ears in pots, the greater bulbs bring about bigger plants. Treat the plants liberally when they are first developing. Throughout the spring and summer, they ought to be treated once each month with fluid compost or utilize slow-delivering cases toward the beginning of the periodKolašinac, S., et al., Challenges and possibilities of organic seed production with the emphasis on control of pathogens.
