2/ pink soba and achocha. 

These grew really well, but nothing really pollinated them. I got no fruit from the achocha even though they grew to be  monstrous vines. Both the soba and achocha were growing adjacent to monarda and globe amaranth which are very popular with pollinators. 

There are just a few viable seeds on the pink soba and they reseed themselves but not enough to harvest as food.
