We’ve pondered this question, attempting to answer it years, with some success as well as many failures.
When we first installed the bluestone patio I had a vision of Creeping Thyme growing between the stones. A childhood friend had a black cement pool surrounded by a bluestone patio with thyme growing between the stones. The origin of my fantasy. It was really beautiful. The pool was situated with a gorgeous view of the Green Mountains. I still think about that pool 25 years later and the Thyme surrounding it.
Anyway, enough of my day dreaming…one key to all plants thriving between pavers is adequately watering after the initial planting. Our garden heats up like a sauna when the dog days of summer kick-in, so watering thoroughly in the mornings keeps these small plants happy.
A few plants I love for between the stones:
- Corsican Mint -releases a deliciously minty fragrance when touched and when it’s thriving it fills in the spaces without growing over the over the stones. See the picture below
- Creeping Thyme. Although this has proven to be an unreliable plant for me between pavers, in some areas with part shade it thrives.
- Hens & Chicks – these are great for growing in a hot spot in a stone wall. See the picture below.
- Mazus – this is a great plant that spreads quickly. One downside, it sends out runners and can quickly cover your stones with its mat-like growth. That can easily be remedied by trimming it back, but it does take a bit of maintenance.
- Moss – this a great filler that you can easily whip up in your blender (more on that a later date) and the cost is minimal.
Once the plants are established and happy I tend to fuss over them a bit less and let them grow on their own.
