burnet, Poterium sanguisorba

Burnet was a very popular green vegetable that was brought to this continent very early in the European immigation. It's flavor is said to be a like cucumber, but a little sharper. Like so many veggies, older leaves from older plants can be bitter. If it is so good, why don't we still find in at the market? I guess it just didn't stand up to the competition from arugula? Is there potential here?
