I mentioned it because this year I had 3 seedlings in a pot and all bloomed. They all set pods but two aborted them. I suspect it was because when I would go out in the morning the pot would be full to the brim with water from overnight thunderstorms. The one that still has pods bloomed much earlier so the pods were much further along. I think the stress of almost drowning made all the pods on the other two abort since they both started blooming the same day and bloomed either mid-late or late. I'm pretty sure that if the weather improves next year they will be pod fertile.
I think some of my seedlings struggle to bloom that first year and are probably not in the best condition. The added stress of forming pods may just be too much for them. I haven't checked to see if seedlings that bloom at two years old abort pods more than ones that wait an extra year to bloom. Even if my seedlings set pods the first year or two they usually only set one or two pods. Later on they will set more pods.
