Is this a good idea? To grow bamboo as a hedge in very narrow containers, to
save space? What variety of bamboo would work?

You can do this, but you will need to keep the bamboo well watered and you will
need to take steps to prevent the bamboo from being blown over by the wind.

Certainly, burying the containers would help. Though probably rhizomes would
escape through the drainage holes you would need to incorporate.

I'd use a phyllostachys variety for a fairly high hedge.
