Does anyone grow this plant for its edible leaves? It is apparently sold in the Asian markets here in the Raleigh, NC area as Gongura leaves and is reportedly very popular for frying as a vegetable in India. I have also read that H. acetasello leaves are eaten in Africa similar to sorrel. I am familiar with 'Red Shield' and 'Haight Ashbury' as ornamentals, but are there other H. acetasellos that would be a better source of edible leaves?
