Seed vs Plant Upgrade

[sacred sinew]

Can someone explain what's the difference between seed and plant upgrade?

There are seed crops and fruit plants available in game right now. You can buy both at Sam’s. The fruit plants are banana, avocado, rambutan, dragon fruit. They become available as town rank increases. Eventually the fruit trees will also be available. Hay will increase animal product quality.

Ohh thank you

Avocado is most definitely a fruit tree in real life, why would the devs group it with banana? Actually I'm looking up rambutan and it looks like a normal tree too
