Octopus Tree on Rock

The Octopus Tree (also known as a Schefflera) is a dangerously invasive species in Hawaii, in particular in Kauai. It hails from Australia and is a fairly common houseplant in most of the US. They are dangerous because they can grow almost anywhere (note that this one is perched on a rock) and their roots can easily choke out other plants. I think this one is kept as an example of how they can grow.
