What blessing would one make on leaves from [woody] trees that are routinely eaten? Is it ha'eitz, because they came from a tree? Is it ha-adama, because they're not "fruit" but are vegetative? Is it shehakol, for some other reason?
Are there any examples of leaves from [woody] trees that are routinely eaten? If so, do any halachic sources discuss what to make on them?
The Shulchan Aruch OC 202:6 discusses the bracha on a caper bush. The caper has multiple edible parts including leaves and berries. The Shulchan Aruch says the berries get a HaEtz because they are the main fruit ("Ikkar HaPeri") and the leaves get a HaAdamah. The Shaar HaTziyun sk 41 says the reason the leaves still get a HaAdamah is because the capers were planted for their leaves as well. He says that when people do not plant the capers for the leaves at all but solely for the fruit than the leaves revert to SheHaKol.
So in short, if the leaves are the main fruit of the tree they get a HaEtz. If they are not the main fruit but still an intended benfit of planting the tree, they get a HaAdamah. If they are completely unintended, they get a SheHaKol.
According to the shulchan aruch harav capers are hoadomo too, being that they are planted for their leaves too.
