This plant grew from seed to about 2' high within 3 months. I'm sure it's not done growing. I have no clue what it could be, since I'm in the bad habit of sticking anything that looks like a seed into the soil. It could come from the grocery store fruit or veggie, it could be a seed that I did not label etc. It's inside a greenhouse, growing in an aquaponics bed. I hope it is edible :-)

    Can you tell us where this greenhouse is to help us narrow down possibilities? Please post a picture of the entire plant as well. Thanks, and welcome to the site!

Also looks a bit like a mustard or rocket plant.
