Long razor sharp thorns.

Not goose claws🫤😄
These things are brutal.
I googled, we have angrešt as gooseberry, but it looks differently. I've never seen other than yellow. But yup, it's like needles. 
There are many different types. I planted two more varieties trying to create a natural fence with them.
How does it work? I was thinking about something similar for our future lot. Thorns are good, for example under low windows, and edible thorns are even better.
Yeah I’ve had a similar time with wild blackberries. I can believe it
Yeah here’s to hoping for the mention of geese, always 🍻
