knot garden plants


I am looking for suggestions for plants to use in a knot garden in a school garden. So far, my list includes lavender (gray/green) and santolina (gray/green). Does anyone have any other ideas - we don't want it to be more than a few feet tall but tough enough to withstand some bumping from the kids.
