Origin: in India as a selection of a native species, Rubus albescens Roxb. Introd. into the U.S. in 1948. Achenes sent to the Univ. of Florida in 1947 by F.B. Harrington of Natal, South Africa; originally introd. from India; then selected plants were distributed to nurserymen in southern Florida. Tree: evergreen; shoots glaucous, with prominent spines; canes vigorous, growing 10 to 15 ft per season; adapted only in regions (subtropical) where freezing temperatures do not occur; apparently more disease resistant than most raspberries; flower to 1/2 inch in diam., petals purplish-pink, in terminal and axillary clusters of eight to many. Propagated by achenes, cuttings, or tip layering (the easiest method). Useful in breeding work and very suitable for home gardens. Fruit: black; covered with soft hairs; flavor mild, slightly sweet, flavor good; achenes small; similar to western native black raspberry; main crop ripens March to May in Florida.
