Beginner Gardening: using Sedum as a groundcover - a living mulch?, 1 by meiow

Hello, wonderful people!

I read an article a while ago about making a 'living mulch' - a low groundcover to cover the flower beds, from what I could tell. I also ran across a note somewhere that sedum can be used on roofs to make them more eco-friendly, etc. And, finally, I read somewhere that sedum will not choke out other plants.

So, I'm thinking about using a few varieties of sedum to cover my flower beds, and forget about mulching.

Is this possible? Reasonable? A good idea?

Attached is a beautiful picture of Sedum cauticola 'Lidakense' from user Happenstance, available in the PlantFiles - one of the varieties I'd be considering. (I want to give credit for this gorgeous picture!)
