Fruit
Rubus ursinus
S tier
Rubus ursinus is the Pacific trailing blackberry—native western North American stock behind many hybrid berries including loganberry and boysenberry lineages. Fruit is elongated, intensely aromatic, and soft when fully black, with a perfume wilder than many erect commercial types. Canes trail and root at tips, forming thickets in mild coastal climates. Treasured for fresh eating at peak, jams with extraordinary aroma, and as breeding parent more than as a uniform supermarket SKU. Berries shatter if overripe; pick slightly firm-black and finish flavour off the cane carefully. Native range from California into British Columbia shapes traditional foraging.
