Low Water Shrubs

The shrubs able to handle dry conditions often have adaptations such as thick roots or an elaborate root system that gets as much water from the surrounding soil as possible. Shrubs suitable for low water scenarios include some native types, but also others originating from other continents. The dry and sometimes rocky spots you have on your property that would look much better with some greenery benefit from the presence of such species.
  1. New Jersey Tea

    • Sandy loam or rocky soil is the perfect medium for a native shrub called New Jersey tea (Ceanothus americanus), a type growing to between 3 and 4 feet. New Jersey tea is round in form, with a compact frame and dense branches. The shrub has appeal during all seasons, helped by its yellow twigs in winter, green foliage and white spring flowers. New Jersey tea's root system is woody and extensive, making it hard to transplant once the specimen establishes itself. As a ground cover on dry hillsides and rocky slopes, this shrub works exceptionally well.

    Mint Shrub

    • China is the origin of the mint shrub, (Elsholtzia stauntonii) -- a versatile plant that grows in dry soil from U.S. Department of Agriculture plant hardiness zones 4 through 8, according to the Missouri Botanical Garden. Mint shrub needs full sun conditions to grow and gives your landscape fall color when it blooms in September and October. The purple flowers emerge on 8-inch long spikes. Crushing the leaves makes them give off a minty aroma. Mint shrub grows to 5 feet and works in a shrub border where dry conditions prevail.

    Rose Acacia

    • The leaves and flowers of the rose acacia (Robinia hispada) are outstanding features, with the compound green foliage having as many as 15 separate leaflets and the flowers coming out in long streaming clusters. The flowers are pinkish to red, with most blooming during May. The ability of rose acacia to grow in poor quality, dry soils makes it a possibility to prevent erosion in embankments and sloping hillsides. The shrub grows to 10 feet high.

    Tamarisk

    • Not only does tamarisk (Tamarix ramosissima) grow without benefit of plentiful water in the ground, it also tolerates exposure to salt, making it usable near the ocean. Tamarisk hails from southeastern Europe and sections of Asia, but it grows from USDA zones 3 through 8. The shrub grows between 10 and 15 feet, with its size making its employment as a screen or a windbreak possible. A combination of leaves resembling scales, colorful twigs and plumes of pinkish summer flowers make tamarisk ornamental.
