The hardiest and most beautiful species is Tamarix Amurensis. In the West this will thrive on dry knolls where no other graceful shrub will live. Its foliage has some resemblance to that of the heath. The pink flowers are in lateral spikes, and the Amur species flowers often three or four times during the summer. If kept in shape, and a full crop of flowers are produced annually, the new growth must be cut back fully two thirds each season in the dormant period. Tamarix Gallica is nearly as hardy and desirable and is most generally planted east of the lakes, and in the South Tamarix Africana is mainly used.
