Hawaiian ginger hardiness
A friend gave me some hawaiian ginger root last year. Looks just like the ginger root you buy at the supermarket. I planted it in a pot and it has been doing wonderfully indoors since, except for the lack of flowers. Is this plant hardy in my area? I've always considered virginia beach simply zone 7, but the USDA map appears to be zone 7B and the garden web zone map seemes to be zone 8. When would be a good time to put it outside and what do I need to do to it to get it to flower?
