Observing plants growing in the wild has always been my greatest source of inspiration when it comes to growing species in the rock garden or other more specific situations (like a scree garden). Growing along the shores of lakes Michigan and Huron on rocky, calcareous substrate/alvars in full sun, there is this little mint scented plant, which seems perfect for the edge of the rockery, or as a groundcover along a patio or walkway. It will bring a much needed splash of colour in mid-summer, not to mention the refreshing spicy mint scent!
Another one that got into the ‘seeds to be collected’ list, which keeps getting longer and longer.
