I would pay a recurring subscription for something that was worth more (to me) than I paid for it.

Edit: After your edit: I would pay a recurring subscription for something that sent me seeds for my garden each season, with some basic instructions and a chart for when to plant & harvest, what to plant together, etc.

Presumably I would have some minor say-so in what kind of plants I was getting, (Root crops, fruits, veggies, sprawling, herbs, etc), but generally I want you to decide what I'm getting and when I should be ready to plant it.
