In California the all-controlling factor is rain, For several months, generally speaking from May to October, practically no rain falls, and plants which are not specially adapted to withstand this long drouth must perish. The grass in the hills is dried into natural hay, and the gay annuals which painted the meadows and hillsides, in spring, with great masses of vivid color, have ripened their seeds and died. Herbaceous perennials have gone to rest until awakened by the first Fall rains, and except for the trees and shrubs, there is little verdure to be seen, and the summer landscape has a very different aspect from that of the Atlantic States. Just as soon, however, as the first rains of Autumn fall, there is a quick change. Sometimes, if the first rain is fairly heavy, within forty-eight hours one can find millions of little seedlings sprouting in the low places where the water has settled, and in a few days a film of tender green spreads over the ground, which deepens in tint as the days go by, and advances up the hillsides, which are soon covered with a dense growth of grass and many sorts of plants which bye and bye will be covered with masses of brilliant flowers. Usually the first good rains come in October, at which time we may say spring begins, to last through the winter months, and finish with the last showers in April or May. There is rarely cold enough to stop the growth of hardy plants, even in midwinter and our gardens are pretty well stocked with flowers all through the winter. Sometimes there is not enough frost to damage even such tender plants as heliotrope and nasturtiums; and in |
