Junipers are one of the hardiest and most drought-tolerant shrubs. These conifers have prickly young foliage, mature foliage is flatter and softer; their foliage can be light green, dark green, silver-blue or have golden hues. Junipers tolerate many soil types but prefer well-draining soil and sunny locations. “Low-growing” junipers range in height from a few inches to about 2 feet, making them a good ground cover plant. They spread easily to control erosion on a slope or to cover an area with poor soil.
