I took the mint out and put them in some starter soil with their own little dome. I started some mini passiflora that I got in a seed trade. They are teeny little yellow ones slightly larger than your thumbnail.
Passiflora lutea - Google Search
I really think I MAY see the bump of a seed tail on a couple of them. They are hard to see because they are the color of the sponge.
