I'm going to be installing about 250 sq ft of thyme and was planning on using Wolly Thyme. The area will be used as a play area for children. I was thinking to add some intrest to the area I might use 2 varieties of Thyme. I chose the Wolly for its low height and tolerance for being walked upon but it lacks the fragrance associated with thyme. Does anyone have a variety that works well in a fairly high abuse situation? Because it is a childs play area should I be concerned about bees being atracted to Thyme, or are there varieties sans flower but still with fragrance?
