I recently read that sweet potatoes are broadly classed as morning

Guess you know that sweet potatoes leaves can be used like spinach.

I do now. Back when I thought that sweet potatoes were potatoes and
thus nightshades I never would have imagined it. The leaves of
nightshade family plants are so varied I would have no idea and no
specific reason to look up the botany article on sweet potatoes.

Huh, so morning glories taking over the garden does still count as all
in the edible topic. I don't recall ever tasting the leaves of a
morning glory flower.
