I never realized there that many types of mint. My guess, judging by the smell, is that it may be spearmint but I'll have to someday check that out. I have it planted in the back where it can pretty much grow wherever as long as it stays outnofmthe rhubarb patch :-). I dug up quite a bit if it (mint) this spring to keep it in check and outnof the rhubarb.
Thanks, yel. I will give that a try. I was worried about the mold but maybe the answer is small bundles like you said.
