Phaseolus lunatus x polystachios
« on: 2020-06-04, 07:06:03 PM »
This is an allopolyploid cross originally done in Florida in the 70s.  Last year a friend sent me four seeds.  The mother was Fordhook lima.  Iím still evaluating it, not sure if itís hardy in the ground but itís definitely perennial. .  Itís worth trying to cross it back to either parent, especially if unreduced gametes can be formed.

I'm interested to hear about whether the hybrid produces seed reliably or if it has any fertility issues.  I have a few P. polystachios seedlings at the moment and if they overwinter here I am interested in crossing them with P. lunatus as well provided there is some indication it would be worthwhile.

I have established patches of P. polystachios growing on my garden fences. They came from a friend in another state and when I first planted them I started some in a cold frame and some direct planted. The direct seeded did just as well as the transplanted ones.

Last fall I identified a large wild patch not far from my house, seeds in the local wild ones, while still quite small are noticeably larger and lighter color than those from North Carolina.  I got the the patch late and only collected abut 1/2 a cup or so, I'm keeping a better eye on them this year to try to make a bigger harvest.

My only attempts at crossing is to plant a single runner or lima bean plant to grow mingled with the P. polystachios in hopes it will just happen on it's own. A big obstacle to this seems to be that P. polystachios are very late to flower.
