RE: Blackberry (Rubus fruticosus and others)

great post ! i love blackberry. I picked and dried a few leaves last year and then added kombucha and water kefir for the 2nd fermentation. It tastes very sweet.
However, I could only recognize it at that time when the fruits were still on. Otherwise, I often worry about confusing blackberry leaves with raspberry leaves or strawberry leaves. Blackberry leaves are white on the underside, aren't they? and the spines are slightly curved and can also be found on the underside of the leaf.
Strawberry leaves and stems are reddish, as far as I know.

I have also read that raspberry leaves and blackberry leaves are often confused in midwifery.
Raspberry leaves are supposedly there to keep the baby inside, so the tissue tightens. Now it is said that these properties are actually attributed to blackberry leaves... and that raspberry leaves could even lead to a miscarriage... I don't know myself.

best regards !
