Creeping thyme get planted in the seams. I chose lemon frost thyme for its aromatic and flowering properties at the far end of the patio. I chose nutmeg thyme for its red stems and bright flowers to go along the border and spill into a neighboring bed. The bulk of the patio - especially near the back deck - is woolly thyme which is super hardy, looks good even with snow, and doesn't flower so it won't attract bees near the back door.
The parallel lines of perforated irrigation hose minimize watering demands plus spare patio furniture from sprinkler watering.
Many thanks to Adam and Tom with Sticks and Stones for perfectly installing the pavers. They rock! (Yeah, that is my worst pun joke ever. Heh.)
