The Tamarisks are large feathery deciduous shrubs or small trees whose foliage is deceptively conifer-like and needs full sun to thrive. They aquired the common name of Salt Cedar because, amongst their many other characteristics, they do very well by the sea. Hailing from New Zealand, and introduced in the early 1800s, there are two species that are commonly planted, Tamarix tetrandra and Tamarix pentandra. These two species look fairly similar, but they flower at different times in the year.
