Invasive Description

Native to Eurasia and Africa, Salt Cedar or Tamarix can be a spreading shrub or small tree, growing 5 – 20 feet tall, with numerous slender branches and small, scale-like leaves. The attractive pale pink to white flowers are small, perfect and regular, arranged in highly visible spike-like racemes. Tamarix consists of several varieties and taxonomists disagree on which species of Tamarix are in the United States. Species are thought to hybridize.

Ecological Threat

Tamarix was introduced to the United States by landscapers in the 1820s  because of its showy flower clusters and feathery appearance. It was also used for river bank stabilization and for windbreaks. By the 1870s the plant had escaped cultivation and was spreading rapidly. Long tap roots allow the plants to reach deep water tables and interfere with natural aquatic systems. Salt cedar disrupts the structure and stability of native plant communities and degrades native wildlife habitat by out-competing and replacing native plant species, monopolizing limited sources of moisture, and increasing the frequency, intensity and effect of fires and floods. It concentrates salt in its tissues which raises soil salinity when the plants die and decompose.

Salt Cedar is on the Texas Dept. of Agriculture’s list of Invasive Plants which are illegal to sell, distribute or import into Texas.
