I live in the Adelaide region and my winged bean plant has just completed a massive burst of flowers and crop. This seemed completely out of season as it was planted at least a year ago, barely survived summer without flowering throughout, survived winter without a problem (which seems to contradict its need for higher soil temperatures), then in mid-August took off with growth and flowers. I've just cut it right back so is it possible it will start new growth and survive another season?

Have a look at this article

I can't find if they are annual or perennial. Sounds like annual. Let them grow and see what happens.

After two weeks with regular watering, it has succumbed to nature, dried up and died, so it's definitely an annual. Contrary to what it states on the seed packet, I will not be starting off new seedlings until towards the end of summer and hoping for a repeat burst of flowers in late winter and early spring. Thank you also Liz for that article... what struck me in the comments section there was this from a Canberra grower.... 'I live in Canberra, Australia, and can report that I sowed some asparagus peas last spring. They didn’t produce much that season but, amazingly to me who had thought they wouldn’t last our winter here, they are flowering profusely and bearing fruit now, the second month of spring. And temperatures this winter got down to -7C!' This is very much how my own plants responded.

Hi, could I grow Psophocarpus tetragonolobus in Ashburton outdoors? if not should I grow them in the greenhouse? Thanks

It is normally grown in hot humid areas so if you like try the green house.

I grow them outdoors here in Dunedin they do really well, but the ones in my tunnel house are much faster

Growing anything in a pot requires a lot more attention re watering and fertilizing regularly. And you would only produce a small amount of produce. Give it a go if you like.

Slow to germinate on Atherton Tablelands (far north Queensland, elevation 900m, so cooler than coast). Seeds available Bunnings.
