The variegated form of the common British Ground Ivy (N. Glechoma) is a very pretty trailing plant useful in the rock garden or border, or for hanging baskets. It has roundish leaves beautifully variegated with silvery white. It grows in almost any moist soil in somewhat shaded positions, and is readily increased by cuttings and division. N. Mussini is a straggling plant now used largely in places for carpeting the ground or as an edging. It is smothered with pale purple or blue flowers in June and July.
