Snowbank White Blackberry.  Snow-white berries are translucent, milky-white in color but have all the flavor of a normal blackberry.  The drupelets look like tiny pearls and are simply beautiful little fruits.  Berries stay whiter than other similar varieties as berries ripen, and with much better flavor.  A vigorous, trailing-type grower with good disease resistance.  Ripens in late July.  Originated in 1916 by Luther Burbank. Self-pollinating. Zone 5-8.  Rooted plant growing and shipped in a 3 inch pot.
