For contrast the dark one and the chartreuse variety. They have fared well through the hot summer. In my absence a drip irrigation system kept them watered.
Yesterday, I saw a flower in the pot and recognizing it as a morning glory flower I bent down to see how such a seed had found its way into the pot. It wouldn't be a surprise to see one growing there because they pop up all the time in the garden, mostly where I don't want them. But this flower was on the sweet potato! I now learn that the sweet potato is not a member of the potato family, but only a distant relative. It is convolvulus, Ipomoea batatas, and this is a morning glory flower! I can only hope it doesn't behave like the other morning glories.
