I if you have a bit of room for climbing nasturtium, would recommend that one. The whole plant is edible tastes peppery. The flowers look great on salad.
As for beets, I am hoping to get my roots going for the fall. If you don't want the purple poops golden beets are a fav of mine. As for growinging info ask nostr:npub1tsgw6pncspg4d5u778hk63s3pls70evs4czfsmx0fzap9xwt203qtkhtk4
