There are no "Elephant Ears" that grow like ditch weeds around Chicago. None

I live 25 miles outside Chicago and can show you Elephant Ears in hedgerows,
in roadside ditches, and in the scrub at the back of my lot.
They're found in vacant lots all over the city* -** i grew up there.

They grow about the size of established rhubarb clumps and will produce
a burdock like seed pod if left unmolested.* The leaves are even larger than
rhubarb and could never be mistaken for tiger lilies.

Don't know anyone who cultivates them as ornamentals tho.
Mostly* -* they get rooted out on sight.
