This plant has sprung up in my neighbors garden. We both grow various jack-in-the pulpits
but can't identify this one. The flower part looks like the pinellia ternata which pops up
now and then. But the rest of the plant looks like many other of the Arisaema Genus we
have growing. These were not planted by us and this is the first year we have seen them.
Could they be a cross between the pinellia and something?
