Ornamental juniper plants add feathery texture to the landscape.
Juniper plants grow in a variety of sizes and shapes and thrive in conditions that often discourage other plants. Drought tolerant and adaptable, they grow best in most well-drained soils. These evergreen coniferous plants produce needlelike leaves and fleshy, berrylike cones. Ornamental groundcovers add color and texture to rock gardens, and shrubs and trees provide attractive privacy screens or windbreaks in exposed areas. Depending on the cultivar, junipers are hardy in United States Department of Agriculture planting zones 3 through 9.
