I've garnered a short list of miniature varieties from poking around, but most were recommended by the vendors. What smaller varieties of cantaloupe have you folks grown and found good?
Minnesota midgets performed well for me. However, they were not in a container.
I've done Minnesota Midget in self-watering containers and they've done well. I do live in Minnesota, so maybe that's the ticket. I grew them up a trellis.
