Alocasia esculata var chartreuse - Plant
This is not a common variety. The regular green to greenish purple variety is commonly seen growing in India. It is usually planted where kitchen washing water flows off. Plants love water and wet areas. It spreads and grows well if given some fertilizer. Even without leaves can be harvested every second week.
The yellow variety too is easy to grow. It is slower growing and is also less tolerant of very harsh sunlight.
