Okay, y'all. Is there a difference between SAHARA MUSTARD and LONDON ROCKET? If so, how do you tell the difference, and does it matter? Are they both invasive? Are they both edible? I ate the top - flower and tender leaves - off some Sahara mustard in my yard and it was delish - hot and sweet. I id'd it as Sahara mustard because that's what everyone says is growing in the desert right now.
