Even if the flower is removed, the edible leaves, stems and roots soon turn tough and bitter.
How do you stop seedlings from bolting?

Can you eat flowering cabbage?
Ornamental cabbage and kale (also known as “flowering” cabbage and kale) are in the same species (Brassica oleracea) as edible cabbage, broccoli, and cauliflower. While ornamental cabbage and kale are edible, they tend to have a bitter flavor and are often used in a culinary setting as garnishes.

What does it mean if a plant bolts?
One of the biggest nuisances in the summer vegetable garden is bolting – when crops put on a vertical growth spurt to flower and set seed before the vegetables are ready for harvest. The result is inedible, bitter-tasting leaves or poor-quality produce with little that can be salvaged.
What causes cracking and bursting of cabbage heads?
It often happens after a period of dry weather followed by a heavy rain. Thirsty roots quickly drink up the excess moisture in the soil, which builds pressure inside the tightly bound foliage that causes heads to crack.
Why are my cabbage seedlings leggy?

Why are my seedlings growing so tall?
Overly high temperatures, such as those maintained over a heating mat or under a humidity (germination) dome, can lead to a rapid growth spurt in seedlings. As soon as the seeds germinate, they respond to the heat by putting up tall, skinny stems before leaf production has a chance to catch up.
How do I stop my seedlings from getting leggy?
As discussed earlier, the best way to prevent leggy seedlings is to make sure the seedlings are getting enough light. If you are growing seedlings in a window, try to grow them in a south-facing window. This will give you the best light from the sun.
