Perennial Beans

       

I never uproot bean plants when they reach the end of the days - not just because they're supposed to have nitrogen nodules or summat on the roots but because they may regrow. 

This is a Gigantes bean and its 4 years old!! Every year it puts up new growth in spring and latches onto whatever it can find. I helped it with a cane this year and its now scrambling into an apricot tree.

I've also had success with Firestorm RBs and Broad beans. 
Worth a try!
