Moss Verbena is native to South America, which means it’s no stranger to sun, heat, or drought. This hardy groundcover makes itself equally at home on slopes and banks, in rock gardens, in planters or hanging baskets. Spring through fall, small clusters of purple flowers attract butterflies and hummingbirds. Moss Verbena's fern-like foliage stays especially low to the ground when grown in full sun, and only reaches up to a foot in height when grown in shade.
