(Just posted to alt.binaries.pictures.gardens)

These things have started sprouting up all over now that cooler
weather has returned. They seem to grow wild. They blossom early in
the morning but begin to wilt when the sun touches them. They are huge
blossoms. (I apologize for using the Coke can; it was the only thing
to hand for showing scale.) The stems and leaves resemble those of
woody plants. "giant morning glory 2012-09-19 08.01.47 pod.jpg" is a
detail showing a pod of some kind.

What are these?

TIA
