They are premier choices for embankments, roadside medians and cascading over retaining walls. They are wind and salt tolerant so lend themselves wonderfully to coastal gardens. Their tolerance to heat and drought makes them ideal choices for the mid-west where traditionally, junipers were the groundcover of choice. Cold hardy to zone 2.
