What's different from day neutral winged beans and regular winged bean ?

Regular winged beans don’t develop fruits during summer because the day time is just too long. It starts to develop fruits in the fall when the day gets somewhat shorter. As in the areas where these beans originally come from. There are day neutral varieties out there that have been modified to fruit even when it’s light outside at 8pm. Regular varieties fruit in the fall but then the cold weather comes and everything dies. With day neutral varieties it’ll start fruiting already in the summer and hopefully give you a crop for long while before the cold hits.

Thanks for your detailed explanation.
