As you can see from the photo, my husband picked a lot of arugula so that it wouldn't go to waste. As I understand it, if the arugula is not picked on a regular basis, it flowers and creates seeds. Incidentally, if arugula is allowed to flower, the seeds are picked and saved to be used again. So he picked it all and reseeded again for another crop. Do you know that arugula survives under snow? Actually in November and December arugula is at its best. I went ahead and removed all the tiny leaves and discarded the rest. Tonight I made a delicious arugula salad.
