The torch ginger, Etlingera elatior, is a very common tropical plant. It has been posted many times in the past. In fact Autumn Belle had lots of information about it last year. However i have some nice photos of different maturities , so we can distinguish the progression of appearance from the bud to the more mature stages. So even if you might find it redundant, i still opted to post it. Some peepers, passers-bye and latecommers like my friend, Ma'ligaya might find them stress-relieving.
The heart (colloquial term) or the growing point inside this blossom can be eaten fresh upon opening. It has lots of anti-oxidant properties because of the phenolics it contains. You might want to try it when you see a banana blossom in the market. You can just eat the heart and cook the rest. As a warning though, you cannot eat the rest of the blossom as it is astringent and slightly bitter when uncooked. Only the heart at the middle is good to eat raw. Happy experimenting!
