My first harvest of dried seed from my 3 vines was divided up and sent back to those in the states who either didn't get them, they died or hadn't produced so far. The first batch of collected seed, the seed coats were a little pebbley to the touch, perhaps from the heat wave that descended on us. The second batch was picked and shelled yesterday, all seed in perfect shape but vary in size according to how many seeds in a pod. The pods that only had one or two seeds in them were the biggest very much the size of Gigandes, the smallest were from pods that had 4 seeds in them, I only had one pod with 5 seeds.

Mixed is fine. I've noticed that most runner beans take several seasons to adapt to my climate anyway. Gigandes may need more time than usual, but since I can't grow it every year, it is an ongoing project. Hopefully Piekny Jas will prove to be a little more cooperative.
Funny how several runner beans have evolved into multi-year projects... I need to find 1-2 more locations to grow them, maybe recruit family & friends to slip a few into their gardens.

I could grow more limas that way too, I'm collecting them faster than I can grow them.
Speaking of Bosnian Pole I'm growing it this year. Last time I grew it was 2013. I checked on it today for dry pods, and noticed a deer had eaten all the top leaves off nearly half way down my pole support. Most of the pods are nearer to the ground. That deer didn't touch a single other pole bean. I hope he or she won't be back.
@Bluejay77 , I am growing it again this year too - with seed from the original 2009 seed increase. The plants are all healthy, and the pods have now begun to dry in large numbers. The first pods had begun to dry just before the "Midwest monsoon" began; I'm surprised that so far, there appears to be almost no spoilage. I could end up with a pound or two of dry seed - but DW has been asking for some shellies, so part of the crop may be eaten by my "dear" as well.
I tried Bosnian Pole last year for seed, but actually used too large a population... and one VERY productive plant in the middle of the row turned out to be a cross. So the seed from the grow out was not saved, but all was not lost - I used most of the crop for frozen shellies. The seed this year, grown in isolation, appears to be all true to type. The black-seeded cross (which produced a pound of seed from that one plant) was saved for possible future selection. Don't know about the culinary qualities, but if that yield can be carried forward into successive generations, it could lead to something noteworthy. If anyone might have time to experiment with it, I'd be happy to send some seed; just send me a PM.
