We found this at a local food bank, and couldn't resist but have no idea what it is. We live in the bay area of California, so there are any number of communities it could have come from. Any help is appreciated :)
In response to comments, I'll give sensory description of the vegetable. There is little smell. The stalks are hollow inside, and crunchy with none of the stringiness of celery. The flavor is light and bitter and reminds me a lot of dandelions.
