In my perennial garden (which is becoming mostly shade because I have overdone the big grasses (Misicanthus Gracillus and Zebrina) I have winding paths of old bricks. Between the bricks I have planted Wild Thyme ( T. pulegoides or T. serpyllum--seeds from Richter) which has not worked out too well because it is much taller and bushier than I expected. Do you-all have any suggestions for something else to put between the bricks. It isn't true shade, and will be less so when I move the grasses, but I thought I would try and tap into this collection of knowledge--and hope nobody minds. Thanks Nancy S deGrazia
