It is slow in the initial development, but later growth results in medium to large, full vines. The stems are thick, mostly green with very light pubescence. Wings are slight to moderate and leaves are dark green and lightly pubescent. White flowers are moderately abundant. Tubers are blocky to oval, slightly flattened with a relatively smooth white to tan skin color.
Lateral eyes are relatively shallow while apical eyes are moderately deep.
Flesh color is a pale yellow to cream color. It is widely adaptable and has a high yield potential. Specific gravity is higher than Monona. Chip color is good at harvest and when stored at 50 degrees or warmer. Norwis is not well-suited to long term cold storage for chip processing.
