Pinellia Pedatisecta

This tall aroid has many spathes blooming from May to late August, and bears a marked resemblance to a "Jack in the Pulpit" with a similar tubular, pale-green spathe and a long whip-like tail. However, unlike many other relatives, this unusual plant blooms almost non-stop from spring through to the autumn frosts and is surprisingly easy to grow, very hardy, and soundly perennial.
