Trifolium repens var. Pipolina. More and more home owners are seeing the advantages of replacing lawn areas by incorporating micro clover seed. As a legume, micro clover fixes atmospheric nitrogen in nodes along its roots. This directly benefits grasses by fertilizing the soil naturally. Healthier grasses maintain a richer colour for longer in the season, and require less water and no further fertilizer whatsoever. Because clover grows so densely, it crowds out weeds, and prevents weed seeds from becoming established.
