Texas has a variety of climate zones that are suitable for a very wide range of native and non-native shrubs. Texas has many native bushes that are suitable for cultivation for landscape design. Because they are native, they have fewer problems with care and pests than other shrubs.
There are many different varieties of acacia, including many that grow as a bush.The Acacia amentacea, or Black Brush, is a dark evergreen shrub that generates light yellow flowers followed by purple seed pods. Acacia angustissima, or Prairie Guajillo, is a short, 3-foot tall acacia that is an annual in northern Texas, but a perennial in the south. Acacia berlandieri, or Guajillo, is sometimes called a honey plant. This variety has dark green fern-like leaves and white flowers. Native Texas acacia are drought tolerant.
Texas supports a number of agave bushes. Agave is a large succulent that grows between 1 and 3 feet in diameter and 1 to 3 feet tall without a flower. Some varieties of agave, like Agave lechuguilla, sometimes called soapbush or shin dagger, can flower on a 13-foot stalk. Agave are good accent bushes, especially in arid or semi-arid areas, or around pools or other bodies of water. Some agaves, like Agave parryi, grow in clumps that look very much like--making them suitable for cultivation as a topiary.
Texas has an ideal climate for cultivating a wide range of mimosa bushes. Mimosa are deciduous bushes that produce pink, white or purple flowers that look like small, spiky pom poms. These shrubs need good sun, but can do well in partial sun. These heat- and drought-tolerant shrubs grow to be about 3 feet tall and 3 feet wide.
