My guess is that it's some kind of tall growing garden bean, and, if so, it's anybody's guess as to what variety. I don't see it listed as a common common-name anywhere. Do the seeds look like beans?

My friend had some pods that she said came from a jack n the beanstalk vine . The pod is a foot long and hard as a brick and the seeds are like red beans on steroids. At an inch or so long . She gave me a bean , I planted it in a pot watered it really heavy and three days latter I have a sprout over three inches tall . The stem is as big around as a pencil . Maybe ill get to see the giant lol

The folks in my part tend to refer to the Purple Hyacinth bean (dolichos lablab) as Jack in the Beanstalk vine, simply due to how blasted big it gets in one summer. The seeds are distinctive: black with a white stripe on one end. Hope this helps:)

I have the same bean plant with the huge seed pods and reddish seeds and lush foliage....anyone found the name of the plant yet? It is not the Scarlet Runner bean; much larger.

dsmith7432, I'm trying to find the real name of this plant as well. Do you have a photo of the actual plant that you could share?

Did it grow?

It's "Castanospermum australe" though, not "Castanospermum australis".
