These big, dark purple, juicy and intense berries first became known to the general public in 1934, introduced by John Knott (yes, the same “Knott” of Knott’s Berry Farm), and it became such a sensation the LA Times called it the “California-developed king of the bush.” Alas, their thin skins and juicy nature make them not very suitable for commercial availability. But that makes them perfect for home growers to pick and enjoy them at their ripest full flavor.
