Sorry, I don't know the answer to your question. Here's a picture of a Hummingbird Moth feeding on my wife's Ginger Lilly. Thanks to whoever ID'ed it on the previous ginger lilly thread.

Here is a link that might be useful:

Vivilet I have planted gingers through October in the fall. The BEST time to plant is really in the spring. You may have blooms by the time fall weather rolls around if you do it that way.

Thanks for the information! I will wait till sping to plant ginger lilies. Does anyone know a good place on the web. to order them from?
