This is a list of plants under 3 feet tall for parking strips. None of these plants need a lot of water. Some of them are xeric plants. The shrubs & perennials don’t spread very much. The groundcovers do spread, but not very widely. The Seattle Department of Transportation (SDOT) requires that plants in parking strips are not more than 3 feet tall. This helps keep pedestrians & cars visible, increasing safety. Don't plant anything but very low groundcovers near fire hydrants.
