What can I plant in between paving stones?
Rather than having a patio or garden path that is one solid block of concrete or decking, homeowners are choosing a more natural and traditional feel by creating patios from flagstones or other paving material. Small ground-covering plants can be used to fill the spaces between the paving stones.
Pennyroyal is the smallest species of mint widely used as a ground cover between paving stones. Roots take easily to small spaces, and leaves are about 1.25 cm (1/2 inch) across with deep green to purple colouring. Small flowers bloom in late summer and range from deep purple to light lilac.
Several species of thyme grow from 2.5 to 7.5 cm (1 to 3 inches) tall, and work well between paving stones as they have tough, fibrous roots and stems that won't be harmed when walked on. Elfin, Woolly, Pink Chintz and Mint are some good "creeping" thymes.
Sagina subulata 'Aurea,' or Irish moss, is a very popular ground cover that spreads bright yellow-green foliage between paving stones. Not a true moss, it flowers in late spring with tiny white blossoms.
Miniature brass buttons
Perfect for moist, shady areas, this perennial has tiny leaves and tends to grow flat. Flowers are also small and greenish. Runners spread quickly and can stop weeds from taking over.
