Trailing juniper is a low shrub or ground cover-type evergreen, native to North America. It can be especially attractive trailing over ledges or retaining walls and very useful on slopes. Junipers are cold-hardy, durable and adaptable plants that can bring year-round color to a dry, alkaline or windy site. The foliage of scale-like needles is attractive, but prickly. In late summer and fall, many junipers have blue-green berry-like fruits, which are actually modified cones, that attract birds. Junipers are widely used in bonsai and are rugged, useful landscape plants. Because they are quite salt-tolerant, they can be used near roads, driveways and sidewalks.
