Somekind of Brassicaceae?, about to bloom, just a wild-wild guest.

The plot thickens. On enlargement I really can't determine that the leaves are opposite. On the long stem on the right in the top pic they're clearly alternate but I can't even tell if that's part of the same plant. Triodonus wasn't an id it was just a vague feeling. The plant appears to be wet which also fooled me to start with. I thought the leaves were glossy but I think they're just wet. If anything the flowers look like asteraceae when blown up. Almost like an aberrant chicory.

I am looking to incorporate some Japanese, Korean and chinese type vegetables because in my area there isn't a Asian store, live in a pretty remote area. I have a huge variety of seeds in my seed library, but im looking to incorporate more of those for 2019. These are some of the ones I am looking for Mizuna (red variety would be nice, it's called Ben Houshi)( also called spider mustard, japanese mustard) Japanese green onion also called negi (sort of looks like a leek) wasabi burdock bitter melon Chrysanthemum Angelica sinensis (also known as female ginseng, dong quai) green onions/spring onions Thai/or japanese green eggplant The list of seeds I have to trade I'll post after this in my profile :) PM me if you'd like to trade.

Maybe a collard or a tree collard. Looks similar, but I don't know. It looks pretty leafy for brussels sprouts to me, at least compared to the plants we grew back in the day, but you never know; it could be. I've never seen such shiny leaves on a Brassica plant, though. Brussels Sprouts and collards are both Brassica, and the same species.
