No variation of plants is more common than those of color, and the color of plants is one of the readiest marks of distinction. We find it scattered through all the classes of nature animate and inanimate, decking with tints of equal brilliance the shell, the gem, bird?, beasts, and reptiles, clouds which attend upon the rising or setting sun, as well as our leaves and flowers, and with no apparent use but that of delighting and cheering mankind with a perpetual display of beauty. - London Journal of Horticulture.
