This is our Doomsday Broccoli Seeds page. It tells how many broccoli seeds one would need on hand in an emergency situation.
Broccoli is a cool and warm weather crop. Some can even be grown in the heat of summer. I have grown broccoli down to 20 degrees Fahrenheit.
Broccoli can be eaten raw or cooked. It is good either way.
One cup of broccoli has about 25 calories. This is not a good
vegetable to live on but it has other good stuff in it. It is rich in
One head produces about 75 calories. You would have to eat 16 heads or 48 cups of broccoli a day to survive. Sixteen heads per day is about 5900 plants per year.
It would be impossible for one person to grow this much in one year. But unless you have a freezer or will be pickling your broccoli, you will not need much since broccoli cannot be canned, because of its low acid content, so it must be eaten fresh. It will only last 24 to 48 hours unless you have a way to keep it cool. Then it will last 4 to 7 days.
Pickling it using a pressure canner will allow
you to keep it for up to one year. I have not tried pickled broccoli
myself so not sure how it tastes. (Just ordered some from Amazon. I
guess I will find out.) (10-20-2018--I received the broccoli. It is a bit hard but tastes okay. I guess it could be cooked longer for a softer bite.)
Let's say you would need 6000 seeds a year.
Seeds from the broccoli will last two to three years when stored dry and properly.
All of the variety information on the David's Garden Seeds® website, including the days to
maturity, color and size are based on data from tests done at specific
locations. Many factors, including geographic location, daytime and
nighttime temperatures, the availability of plant nutrients, many unknown climate factors and insects/pest interact to determine a variety's
performance. For information on which varieties will perform best in
your area, we recommend that you contact your local county extension agent or a Master Gardener.
