Red Raspberries (primocane bearing)
Primocane-bearing red raspberries bloom in early August and produce fruit from mid-August through the first heavy frost or freeze.
Autumn Bliss: Extremely high yielding and vigorous. Canes have a large diameter and are of medium height; they tend to sucker in clumps around original plants. Ripens about 2 weeks earlier than Heritage, although overall productivity is similar in most years. Might be useful in the northern tier of Pennsylvania.
Autumn Britten: Large uniform fruit with excellent flavor. Cane density is lower than average, so plants should be planted slightly closer together than usual (18 to 20 inches between plants).
Caroline: High-yielding plants due to the production of many suckers. Yields 1 to 2 weeks earlier than Heritage. Fruit is dark red and conical and has excellent flavor.
Dinkum: Flavorful, firm, rounded fruit. More susceptible to damage from leafhoppers than other varieties.
Heritage: A medium-sized, firm fruit of excellent quality. Season begins in mid- to late August in Pennsylvania and continues through severe frost or freeze. Fruit tolerates light frosts well. Plants are very vigorous and sucker well. This is the most widely planted red raspberry variety in Pennsylvania; it continues to be the standard among primocane-fruiting types.
