I received this rhizome and planted it, the label was impossible to read but may have the word "superb" in it.
Since planting it has grown beautiful lush leaves and is growing rapidly. I live on the Gold Coast, Queensland, Australia if that helps at all. We've had heaps of rain, it's very hot at the moment and it seems to be thriving, would love to know what it is to take better care of it. Thanks !
