There are many edible leaves, and many fruit tree leaves can be eaten, but the taste is different.
We often eat acanthopanax senticosus, ginseng leaves, tender buds, mulberry leaves, Toona sinensis leaves and so on. I have also eaten willow buds, elm leaves, hawthorn leaves, medlar leaves and so on.
Young leaves of many trees are edible, as long as they are non-toxic, but they taste different, such as sour, bitter, spicy, astringent, sticky and slippery, so you can choose according to your own situation.
