I found these bulbs today. I was digging a hole in one of my gardens to place one of my plants for the winter and this is what I found. Last year I had a Hibiscus Rosa-Sinensis in this location & it had died. But from what I read on the web, the hibiscus does not grow from bulbs. So does anybody have any idea what these bulbs might be. It may be something I had years ago but I can't remember what else I had planted in that area. Thank you in advance for anyone's help.
