There was quite a bit of variation in growth habit, leaf form and colour. Early tuberization was found in all three seed sources which surprised me as I was expecting it to be pretty much non existent in the tropical source. However, it is possible that they are growing shorter or more 'day neutral' varieties in the tropics as well. That said, there was more of a tendency toward longer vining and later flowering in the tropical seed source than in the Swedish short season derived one.
Some of the short season seedlings were very florific! These also tended to set the most pods. I'm looking forward to what that means in coming years. I did get flowers and seeds off of my short season slips as well though less.
The best pod forming row was the one with the seedlings and short season slips by far! The two other plots that contained no seedlings set seed minimally. Our Farm had a decent seed set though said that one end of their row produced seeds much better than the other. This is almost certainly because the right 'parents' were there. Purple seems to be a good pollen parent. The other farm site suffered more from flooding and hail than the other two locations so didn't get any seed set.
I did some minimal pollen transfer at the beginning of the flowering season but mostly left it up to the plentiful bee population. There were bumble bees, various native bees and honey bees visiting the flowers. They were often frustrated by how quickly the flowers closed. You could see them trying to enter the flowers that were already twisting shut by mid to late morning. The lack of sunny weather meant there were probably less opportunities for pollination but still I managed to get a fair number of ripe pods and seeds.
Most pods contained 1-2 seeds though the occasionally one had more. I inspected frequently so as not to lose ripe pods in the abundant leaf cover and litter below. Once the stem connecting the pod started to yellow, the pod was ready so I tended to harvest at this point.
