Oh you have done so well with this theme. Beetroot this colour yes....but sweet potato ....no I have never seen it, but there again I haven't been looking lol.
Well purple sweet potatoes sound better than beets to me. very cute. Glad the color stays purple. I was excited to get purple beans once. So disappointed that they looked like regular green beans when cooked.
it's taro i think, very similar to the one grown in the old country called ube or purple yam. although the soup looked like beet soup to me. aces on the setup.
