what is in my swale?

Need a hand to ID this. And any additional info or uses if anyone has it. Pic from today, front range CO, 2ft tall, pinky nail flowers.

Arugula? Radish? What do the seed pods look like? You can cross off a lot of brassicas because of the white, not yellow flowers, but it looks like something in the brassicaceae family.

DOES look like arugula flowers, but not leaves. Maybe a wild variety? No seed pods yet. Hmmm

It does look like a brassica to me too. My first thought was radish. If you snap off the ends with the flowers how do they taste? And how does the root smell?

At first tasted like kale (2sec), then radish... my only plant, so I wont check the root. But, now I do remember sowing daikon radish. Never thought it would look like that.? Good idea to taste it!

I've had radishes turn viney like that when they go to flower. In my experience, it is more likely to happen to spring planted radishes that bolt before they have a chance to develop a big root. When you do pull it, you will probably see a stringy, fat root that has very little resemblance to a good eating radish.

Save the seeds on it and plant them around Labor Day and see what you get. If it is a daikon, you might get an impressive root before winter really sets in on you.

Totally explains it. I will look forward to saving some seed and resowing in the end of summer! Nailed it guys, thanks.
