Q.weeping cherry tree
Does a weeping cherry offer edible fruit?

This is a very complicated question, and I am afraid there is no simple answer to that. Generally, the fruits produced by a weeping cherry (Prunus subhirtella var. pendula) are considered edible and can be eaten both raw or cooked. Other specialists claim that you can eat these fruits, but they have a very small nutritional value and there is no point. Also, the seeds of the weeping cherry fruits contain poisonous substances like prunasin and amygdalin, which make the whole thing taste bitter and not very tasty. But I don't think they are dangerous to you. But I've also read about some types of weeping cherry where the fruits are poisonous (I'm not sure if that is true though), so I would be careful and I would consult with some kind of professionals - http://www.gardeners-melbourne.com.au/tree-services/ before doing anything. Better to be safe than sorry.
