In a light, dry soil and sunny position this shrub does well as a wall plant, for which purpose it is one of the most ornamental. There are several good nursery forms, of which the following are amongst the best: C. azureus Albert Pettitt, C. azureus albidus, C. azureus Arnddii, one of the best, C. azureus Gloire de Versailles, and C. azureus Marie Simon. California, 1848.
Two other beautiful species found hereabouts are the aster azureus, which blooms from August until after frost, with a slender but stiff and roughish stem, and many bright violet-blue flowers with short rays; and the aster Shortii, or Short's aster, which is found on banks and along the edges of woods and does not usually bloom until September.
A shrub of 4 feet in height, with deep green serrated leaves, that are 2 inches long and pubescent on the under sides. Flowers white, in axillary panicles, and produced in great abundance. This is one of the hardiest species, but succeeds best when afforded wall protection. C. AZUREUS. Mexico, 1818.
