5/5
If you want to learn more about this, check:
- "Rubus fruticosus" (genus and species of the blackberry). You could also go for "Rubus spp." as it's a bit of a messy genus with different species that are sometime much similar
- "Humulus lupulus" (Hops)
- "Leaf morphology" if you want to nerd the thousands way to talk about leaves (I'm not there yet).
- Well and of course, just go outside and observe, next time you come accross these plants. You can also prepare and eat them.
