How tall does draft hollies grow? Is there a species that grows taller than others? I would like to plant some that does not grow higher than three to four feet.

You will have to be more specific. I don't recognize this as the name of a plant, except the 'holly'.

One of the great benefits of using ground cover is less weeds. I have never seen a weed amongst any of my ground cover, no matter what variety. I feed everything with fertilizer so it is all very dense. I guess that is the reason. But another good point for profilerating ground cover if you are a tried and true gardener.
