Tired of growing the same old potatoes (Solanum tuberosum) in your garden? Why not give these 9 blue and purple potato varieties a try this growing season? Most varieties originated in South America and their color in both the skin and flesh comes from the same anthocyanin pigments found in blackberries, concord grapes, and red cabbage.

Caring for Blue Potatoes

Unless addressed specifically, the planting and care of blue and purple potatoes are the same as white or gold-flesh potatoes in the garden or in containers. Purchase seed potatoes at a home and garden center. They may not have some cultivars but search online seed companies and you'll find a great variety. They are susceptible to the same pests and diseases and are harvested in the same manner.

When selecting blue potatoes for the garden, chose the cultivars that are best for your growing conditions and read the information provided with the seed potatoes. What size potato will be produced? What is the growing time from planting to harvesting? Consult your local state agricultural extension office for great information about what grows best in your locality.
