The minute leaves of this flat carpeting perennial are the perfect filler for cracks between flagstones in moist, shady areas. Tiny greenish flowers. Runners quickly fill in and help to keep weeds out. May be used as an evergreen lawn substitute over small areas. Easily divided at any time by digging up the clump and ripping apart into small pieces. May become dormant during summer droughts, greening again once watered. Expected performance in regions with hot and humid summers is not known at this time.
