Leaves are bright, medium green, smooth, and moderately pubescent with prominent wings, large asymmetrical primary leaflets and numerous secondary and tertiary leaflets. Flowers are profuse with green, awl-shaped, pubescent calyx lobes, pale lavender corolla, orange anthers and abundant pollen. Tubers are oval to round with light to-heavy scaly netted skin, moderately shallow eyes, and white flesh. Tuber dormancy is medium-long. With high yield potential, high specific gravity and uniform tuber size and shape, Atlantic is the standard variety for chipping from the field or from very short-term storage.
Tubers are susceptible to internal heat necrosis, particularly in sandy soils in warm, dry seasons.
