Of the eighty-five species known only a few are grown in anything like large numbers. The New Zealand Daisy Bush (0. Haasti), is probably the hardiest and best known with its grey-green Box-like leaves and masses of white Daisy-like flowers in August. It is easily increased by cuttings and from seeds. 0. stellulata (Eurybia Gunniana), from Tasmania, has whitish branches, lance-shaped coarsely toothed leaves, and white flowers in September. Other kinds are dentata, Forsteri, in-signis, macrodonta, nitida, nummularicefolia, ramulosa, and Traversi, all rather tender in most parts of the kingdom.
