I checked on my seed producing bed this evening and I have that in one location and nearby that I have a few small patches of wild sim planted.
One of my wild sim plants, was a 3 pronger, and the top had been blown over or knocked over somehow... and it about half way broke the stem just above the ground. the top was mostly laying on the ground... but if you check the stem you can see where it is bent at a very sharp angle...
And it had Red Berries on it.
I think that most fruiting plants have that ability... if the plant becomes unusually stressed, damaged, etc... the fruit will ripen quicker.
I know that Tomatoes can do that. I had one of my tomato plants get blown over this year (very windy storm) cage and all, and it about half way broke the main stem on the plant. Those tomatoes ripened a week or more before the others.
I am sure that Seng can do that same thing. It sure looks like this one did.
I did find one plant in my seed producing bed that was looking quite stressed out and it had ripened its berries too.
Many others that were looking healthy and well, still had green berry pods.
