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]
