I have recently purchased an australian willow myrtle (peppermint willow) and was just wondering if anyone else has one of these trees in their garden. The plant did not come with instructions at all, and to make things more complicated, i'm getting some conflicting info about the care. I've read that they are container trees in zone 6, and then again read that they can handle planting in zone 6. Does anyone have this tree? And if so, is it in the ground or a container? Thanks all!
