The white blackberry is an unusual white variety of blackberry developed by plant breeder Luther Burbank,[1] also known as the iceberg white blackberry or snowbank berry, probably originating as a pun on the name "Burbank".

He originally found a wild pale coloured blackberry in New Jersey, named 'Crystal White'. He then mixed that berry with the Lawton blackberry, and then other pale berries.[1] Burbank had tried out 65,000 unsuccessful crossbreeds,[2] at his facility in Santa Rosa, California, before achieving success in 1894.[3][4]
