Rascal, the green and white EE's are Mickey Mouse Taro: Xanthosoma atrovirens.
I used to have a lot of EE's, but so many don't like the cold here. I have a Mickey Mouse that showed up 2 summers ago and grew quite large. It had been years since I saw one there and didn't think it was alive. It died back last winter and didn't come back this last spring. My dogs have that yard now and there's digging going on. One dug up a huge root ball and just left it laying there (how could she?) I planted it in my barn yard garden and hopefully it will come back next summer. Don't know if it was the EE or a ginger. We'll see.
