- History & LoreHistory:The genus Rubus includes many different plants collectively known as "brambles" because they share viney growth and wickedly sharp thorns. This species is native to California and Oregon, named from the Latin for bear, the local wildlife that fed most heavily on the fruit. This thornless form was developed in California from the 1923 cultivar, 'Boysen'.Lore:The name blackberry is a misnomer because this isn't a true berry. It's a drupe, an entirely different sort of fruit.
