I find "rec.gardens.edible" to be rather specific appellation. Seems to me
that controlling morning glories in a -vegetable- garden quite satisfies that

In the part snipped the morning glories took over and strangled the
edible plants. It's possible for a garden to hold both types.

I recently read that sweet potatoes are broadly classed as morning
glories. I was barely aware they weren't in the nightshade family
before that.
