A few plants have just sprung up in a couple of neglected pots.
They are either canna or hedechium but having looked at the leaves of both
canna and hedechium I can not see any particular difference.
What way can I distinguish between the two?

Cannas tend to have somewhat broader leaves. Wait a bit longer and this will
be more visible,
The rhizomes of hedechium are more like that of an iris.
