The word "repens" translates loosely to "hasty, unexpected," and is well suited to Veronica repens, aka Creeping Speedwell, a fairly fast growing ground cover that is often covered in dainty white flowers in the springtime. Tolerant of light foot traffic, Creeping Speedwell can be tucked in between paving stones or scattered throughout a lawn, adding random spots of fresh green, mat-like foliage and tiny flowers. Only an  inch tall, this evergreen ground cover can spread to 18 inches wide, and will fill narrow borders or cascade over the edge of container planters and hanging baskets. It thrives best in sunny locations with regular water and is usually ignored by deer and rabbits.
