Once I had some bolting, I either saved it for seeds or cut some for a special-occasion bouquet. But she wasn't impressed by "Chinese cabbage blossoms".
That was before I learned about online seed-trading and gave it all away within my manufactured-home park. I never saw any sign that anyone did anything with any of that seed.
Now I know to sow it thickly for baby leaves, or isolate and save seeds for giving away online (to people who will use them!) but have not had any bolt lately.
