Sweet potatoes can be yellow, orange, red and even purple in color.
You need a good root to start with and then they are easy to grow.
Sweet potatoes like 4 months of really warm weather. They do like full sun unless it is a really hot place. Then they would prefer a bit of shade in the afternoon.
You can do a lot with sweet potatoes. You can bake them and have them with butter. You can have Sweet Potato Pie. You can put maple syrup on them, or brown sugar or even marshmallows.
They are not like white potatoes. They are like Morning Glories. Strange, but some plants just don’t go along with being in the same group as other plants that look like them.
In the US, sweet potatoes are traditional fare at Thanksgiving.
