Using Serbian yarrow as a groundcover
Serbian yarrow forms a low mat. It fills in to a moderately dense cover. It takes light foot traffic, fine to step across occasionally, but not a play-lawn. It holds strong cover through Front Range winters, so the ground doesn't go bare. On a slope it helps knit the soil together and control erosion.
Planting & establishment
Water weekly first summer. Tough silver mat once established.
