Full title: Potatoes and tomatoes are actually in the same family. Potatoes also produce a fruit that looks similar to black cherry tomatoes, but is deathly poisonous. In fact, the entirety of the potato plant is poisonous, outside of the tubers.

Commercial farmers can be fined in my country if they keep potatoes from one harvest to the next. Even small scale. Every year is a race to buy seed potatoes.
A few years back, I read a cover of the case of a young farmer that decided to scale the production of a type of potatoe his grandfather planted every year in his small personal garden.
Because he scaled the production to commercial viability, he got visited and inspected by our agricultural department and faced serious charges, penalties and fines for producing and selling potatoes with no prior traceability. It took serious proportions and it was headed to courts.
This logic bleeds into private gardens and police sometimes approaches people planting their potatoe patches for proof of seed purchase.
It is mafia like.
