This variety has not been observed under environmental conditions outside of southern Texas. The plants of Clark Gold lack anthocyanin pigment through all tissues, including the fruit, which is yellow at maturity, unlike the dark fruit of typical blackberry varieties. Plants have three distinctive characteristics which distinguish it from their parents and other blackberry varieties.
