I agree with you on the last photo. Sorry but I just assumed they were in the generic ginger category without looking at them. And I agree, that category should only have photos of that species.
Good link on eating the foliage, thank you. I lost one favorite ginger in our hard freeze last winter. Its' foliage was so fragrant with ginger when you brushed it but no edible roots. The foliage was used to wrap fish and other vegetables when steaming. It imparted that flavor to the food. I never got a positive ID on it and do not recall where I got that one.
I personally like the blooming gingers as ornamentals. They do take up a lot of space but when they deliver their beautiful fragrant blooms all is forgiven.
