It is not unusual for the September Red raspberry to ripen in some Southern states as early as August, however, the deep flavor is sharpest in September when fully ripe. The berries are a pleasantly bright red color, and the sweet aroma accents the distinctive taste. The September Red raspberry plants are often planted at "pick your own" operations along with Fall Gold raspberry bushes and Black Hawk raspberries to offer a broad selection of colors and flavors to customers. September Red raspberry bushes will grow in many northern states and are very cold tolerant to below freezing freezing temperatures.
