Tamarisk (Tamarix dioica)
They are evergreen or deciduous shrubs or trees growing to 1-18 m in height and forming dense thickets. The largest, Tamarix aphylla, is an evergreen tree that can grow to 18 m tall. They usually grow on saline soils, tolerating up to 15,000 ppm soluble salt and can also tolerate alkaline conditions. Tamarisks are characterized by slender branches and grey-green foliage. The bark of young branches is smooth and reddish brown. As the plants age, the bark becomes bluish-purple, ridged and furrowed. The leaves are scale-like, 1-2 mm long, and overlap each other along the stem. They are often encrusted with salt secretions. The pink to white flowers appear in dense masses on 5-10 cm long spikes at branch tips from March to September, though some species (e.g. T. aphylla) tend to flower during the winter.
