Wow--This is what I am doing next spring on my easement strip! I'm going to use Mother of Thyme, because it is much hardier up here in Milwaukee. There is a thread from about June of this year with pictures where I ask a whole bunch of questions about this. You may want to check it out, though I don't know how you'd track it down. Congrats and good luck--it looks great!
I love thyme gardens, and yours is lovely. I appreciate how you showed your garden preparation and propagation area. It gives folks a good idea of how to get started planting a larger thyme garden.
