They have cultivars that produce in just 3 months so as long as you have 4 month above freezing you can find a sweet potato cultivar.

I grew some this year and had about the same yield as orange and white ones. The plants did seem to grow faster than the others. Thought it would just be a novelty, but i think they are my favorite for flavor and texture.

I prefer the taste of the orange ones myself.

It might be interesting to investigate the nutritional properties of the various sweet potatoes. There are aid organizations in Africa who spread the more healthy types that contain more vitamin A and beta-carotene. This has resulted in less blindness and healthier people.

When yeild and input costs are similar, it make sense to grow the most nutritious food possible.
