QUICK-to-grow, this effortless little groundcover features adorable foliage nubbins that withstand light foot traffic - making it an excellent low-water lawn substitute! Trim it back to create a dense mat and leave the trimmings to root and grow - you’ll increase your stand AND have enough to share! Growing to no more than 6” high by up to 15” across, it erupts in a froth of delicate star-shaped white blooms Summer thru Fall. Absolutely perfect for a green roof, rock garden, parking strip or for filling in a large container. Performs best in well-draining soil but will tolerate clay. Fine with low or no water once established. Attracts butterflies!
