Let's not assume your daughter's plant was not cross-pollinated just because she didn't have another similar plant on her property. There could be any number of similar plants 'as the bees fly'. Besides, each plant is partially self-fruiting, as
@Horntoad mentioned and will make fruit; with cross-pollination the plant produces an abundant crop.
Please, let's not call the berries 'edible' because some people who read this may decide to pop a handful of fresh berries into their mouth. The berries must be cooked in order to be safe to eat.
Thanks
@dyzzypyxxy but I don't want to look online for plants. I prefer to look on the road side, in the field, over the fence, at local swaps, places like that where things are free or freely shared by others.
