Loganberry Floricane Thornless(Rubus × loganobaccus), early season, is a hybrid of blackberry (Rubus ursinus) and raspberry (Rubus idaeus) The loganberry was derived from a cross between Rubus ursinus (R. vitifolius) 'Aughinbaugh' (octaploid) as the female parent and Rubus idaeus 'Red Antwerp' (diploid) as the male parent (pollen source). It was accidentally created in 1881 in Santa Cruz, California, by the American judge and horticulturist James Harvey Logan (1841–1928).
The vines or canes of the Loganberry grow entirely unlike either the blackberry or raspberry. They trail or grow upon the ground more like the dewberry. They are exceedingly strong growers, each shoot or branch reaching a growth of eight to ten feet in one season, the aggregate growth of all the shoots on one plant amounting to from forty to fifty feet.
The canes or vines are very large—without the thorns of the blackberry bushes—but have very fine very soft spines, felt like fur. The leaves are of a deep green color, coarse and thick, and also like those of the raspberry. Early season. The fruit is as large as the largest size blackberry, is of the same shape, prolonged, with globules similar to that fruit, and the color, when fully ripe, is a dark bright red. It has the combined flavor of both berries, pleasant, mild, vinous, delightful to the taste and peculiar to this fruit alone.
It is excellent for the table, eaten raw or cooked, and for jelly or jam is without an equal. The seeds are very small, soft and not abundant, being greatly different from both its parents in this respect. The vines are enormous bearers, and the fruit is very firm and carries well.
