For fun, you might plant a bulb from the grocery store- I found them labeled Yautia and edo/eddo. Dirt cheap. Somewhere I have notes about what each botanically probably are. One a Colocasia, the other a xanthosoma? Neither made runners their first year at least.
I had a dark EE given to me as Black Magic but mine was certainly a Runner.. those rhizomes! One survived winter in Maryland zone about a 7.
