The very fact to note that there are a huge cultivars and hybrids on Alocasia which indeed and impossible task to list down, let alone to identify accurately which proves futile in my part.
However, I would like to list down what I want to have in my garden - labeling their identity at the closest I can identity based on their family or genus - which may not be that impossible.
Here are the list of the plants - specifically these Alocasia which I had managed to cultivate and grow in my garden. However, Alocasia have similar foliage traits and characteristics with Taro but not cultivated for food crop as they can be poisonous. Here - it's more cultivated for ornament purpose and therefore I suggest to do proper study and research if in the intentions to identify to grow edibles.
These are the outdoor variety which appears to be much hardier and easy to grow in comparison the the sensitive type known as Jewel Alocasia (which I had placed in a different category)
These variety are much larger and hardy in comparison which often labelled as Elephant Ears - often planted outdoors which receives open bright sunlight and rain.
on their Care and Cultivation on each plant types and their characteristics.
