This is a choice of plants question, not a landscaping one. Try the Perennials Forum. And you must include your zone and general location to get any helpful responses.

3/4' front-to-back bed depth!!! ...??? That will never work! 3' is about the minimum and more is better.

I can go 9.5 at the most, then I run in to the sidewalk on the south side.

I figured 4 because that comes out even with the bottom of my steps.

I get it ... in your first post you say "3/4 foot". But what you mean is 3 or 4 feet. Sorry, have to take people literally cuz sometimes they mean what they say. Without a photo can't suggest more than try to keep it simple. Other than that, check with Perennials as suggested for specific plant recs.

yep, I do want to keep it simple.

I'll see about getting a few pictures in a day or so.
