I am interested in both of these myself actually!
I just moved to a new home and have a long strip of shade garden that needs to get planted next to a walking path along the North Side of my home (back wall). It literally never sees the sun but is open fully with no
trees near by. Decent light as far as full shade goes.
Might as well make it edible AND beautiful. The ramps might go well under the fruit trees I have been... and will continue to put in.
