This is just a short post. As what Diana has mentioned, the purple sweet potato does go into a flowering frenzy. The flowers are very pretty, almost morning glory-like. Since the container is small and I probably won't have any chance of getting any sweet potatoes out of them, I just let them be and flower on. The leaves are palatable, and even those that felt like very tough or fibrous turns very soft and spinach-like when blanched in boiling water.

The flowers only last for a day, and if it rains, the delicate petals will get damaged and basically clump together. There are no seed pods as sweet potatoes are known to be notoriously self-incompatible. I guess this can be counted as a vegetable cum flowering vine in the garden. If it does produce tubers at the end, that will be an added bonus. For the time being, it looks good, despite being a little messy running all over the place.
