A Typical Spike of Improved Watsonias
Mr. Burbank's improved Watsonias tend to bear the blossoms somewhat more compactly than was the custom with their progenitors. This picture shows a fairly typical cluster. Hitherto selection has been directed largely toward the improvement of the colors. It is probable that more marked improvement in other directions will be shown in the future.
