Rosara potatoes are a high-yielding, red-skinned variety with smooth, shallow eyes and creamy white flesh. They are medium to large in size, with a round to slightly oval shape, making them ideal for boiling, roasting, and mashing. The plants produce vigorous green foliage and show good resistance to common potato diseases, including late blight.
