DescriptionThe density and flowering of California-poppy (Eschscholzia californica var. peninsularis Green), amount of bare ground, and occurrence of other plants were studied in an old field and a stubble field near Madera, California. The stubble field had more poppy plants per unit of area, more plants flowering, and more bare ground than the old field. The two fields differed in how often other plants were found. The results suggest that a site disturbance that produces a harsh microclimate or reduces competition or both will favor California-poppy and that this variety tends to associate more readily with certain plants than others.
