Doomsday Sunflower

This page is our doomsday sunflower page.  It tells about using sunflowers in a doomsday scenario.

Sunflowers are a must in an emergency situation.  Their seeds are enjoyed as a snack by humans, with small seeds used as birdseed. Sunflower oil is used in cooking, paints, varnishes and plastics, soaps, detergents, surfactants, adhesives, fabric softeners and lubricants. The sunflower also shows potential as an alternate fuel source in diesel engines.

Their blooms attract bees and you know bees are a necessity for pollination of your garden plants. These bright flowers are generally easy to grow and come in a variety of sizes and colors, not just yellow.

One drawback is they will only grow when it is warm.

Doomsday Sunflower Numbers

Based on a 2000 calorie diet, we would need about 3 cups of seeds per person per day if this was the only food you had to eat. (If you are a smart survivalist, you will have plenty of other seeds to grow for a decent diet for your family, right?)

The mammoth giant sunflower head will produce about 1/2 cup of seeds. 

So to feed one person per day, one would need six heads per day. 

This would mean in one year, one person would need 2120 plants per year. 

For seed saving, we would need about 25 plants (100 seeds per head).

Following our 1/3 rule (1/3 for current planting, 1/3 for next year, and 1/3 for emergency) we would need to plant 2220 sunflower plants.

Survival Tip: Make sure you hide your seed cache in different places.

Seeds for eating can last for years just by keeping them dry.

If you have an oil extractor, you can grow more sunflowers for oil.  How many plants you would need for this is beyond my ability to calculate. Happy growing!
