Arugula blossoms

Over at Apartment Therapy’s Kitchn they have found a use for flowers from bolting arugula. I got tons of bolting flowering arugula. Unfortunately, all that bolting arugula looks kinda weedy to the untrained eye. I know this because young men came to my door offering their services to pull out all those ‘weeds’. Not the first time someone has done that.
I am trying to collect seed from these bolting plants so I don’t have to keep buying seed. When the seed pods have dried, I’ll pull up the plants and restart my salad days again.
