Gee, people usually ask the opposite question, how to get a vegetable out
of these plants before they bolt to seed!
Long days will make them bolt. Ditto, drought or almost any kind of
shock, e.g. transplanting from flats or some really cold nights. They
are insect pollinated, and readily cross with each other. You can get
an awful lot of seed from a few plants. It's easy to hand harvest -
hang the plants upside down to dry, crumble the seed pods in your hands,
strain and winnow.
I'm at 43 degrees north latitude and can't get a spring sown crop without
a lot of hassle, so I grow them as a fall crop.
