Narrative
This is another blackberry-dewberry which since it partakes most of the blackberry parent, is usually listed with blackberries, The variety is grown very little in New York and the East because it is too tender to cold, but it is a standard bramble fruit in California, esteemed both for its healthy, vigorous, productive plants and for its enormous, handsome, richly flavored fruits. Well grown, the fruits are said to be larger than those of any other of the cultivated brambles. The plants of Mammoth are remarkable in that the canes grow upright several feet and then begin to trail, sometimes attaining a length of 25 or 30 feet. The canes are stout and covered with small, short spines. The plants are propagated from tips and usually fail to come from root cuttings, the method of propagating blackberries. The leaves are semi-evergreen in California. The blossoms are self-sterile and the loganberry is usually set for cross pollination. TYwo other varieties very similar to Mammoth are offered by nurserymen under the names Tribble and Cory Thornless. Californians say that they are distinct, however. The canes of the Cory Thornless are said to be thornless or nearly so. Mammoth was originated by Judge J. H. Logan, Santa Cruz, California, and is supposed to be a cross between the Texas blackberry and the western dewberry. The name was added to the list of fruits recommended for culture by the American Pomological Society in 1909. The variety has often been confused with Bartel which has also been called Mammoth.Plants very vigorous, semi-trailing, tender to cold, unproductive in the East, but very productive on the Pacific Slope, healthy; propagated from tips; reported that it cannot be increased by root-cuttings; canes very long, cylindrical to slightly angular, green mingled with a tinge of dull red, pubescent, glandular; prickles variable in length, small and short, unusually numerous, purplish red; leaflets 3, large, ovate, dark green, rugose, pubescent with dentate margins; petiole short, thick, very prickly. Flowers self-sterile, very late, in loose leafy clusters; petals white, oblong; peticles prickly, long, thick, eglandular; calyx tomentose, eglandular. Fruit early midseason, resists drought very well, said to ship poorly, very large regular in shape cylindrical-conic glossy black; druplets medium in size, very numerous, with strong coherence; core soft; flesh juicy, tender, rather sour until fully ripe when it becomes pleasantly subacid; quality good to very good if properly ripened.
