Growing Sunflower Seeds


Let’s Get To Growing Some Sunflower Seeds

Sunflowers - the fourth sister

Remember the Three Sisters – corn, green beans, and squash?  Well, ancient Indian tribes in the regions of Arizona and New Mexico added growing sunflower seeds as the fourth sister – to draw pollinators to their crops.

It is believed that sunflowers were first cultivated in Mexico about 5,000 years ago – even though wild sunflowers were thought to have originated in the southern United States.

They didn’t gain popularity until being introduced into Russia in the 1700’s.  Then in the late 1800’s, this beautiful flower – shaped and colored like the sun, its namesake – began gaining fame in – you guessed it – back in the good ole U.S.A.  The variety sold in the seed catalogues at that time was none other than Mammoth Russian.


Besides Being Attractive, What Are Sunflowers Good For?

The most obvious?  The seeds make great snacks.  Roasted or raw, salted or not, they contain a hodgepodge of high fiber and an impressive mixture of vitamins and minerals.  I can eat them all day long!

Indian tribes used to grind them into flour to make cakes and bread – to be consumed along with their Three Sisters harvest.


Sunflower oil is used as an inexpensive cooking alternative to olive oil.  It was one of only a couple of oils that were permitted for use during Lent.

The oil was also widely sought after as topical ointment for skin and hair.


Fresh and dried sunflower roots were widely used by Zuni medicine men.  These Native American Pueblo purveyors of medical remedies in the Zuni River Valley chewed the roots and applied them as a poultice to rattlesnake bites after they had sucked out the venom.


The sturdy stems could function as a building material in primitive structures.  But, if you don’t feel like building a “sunflower house”, you can always eat the stalks – as they are prime candidates for a healthy sauté.

Sunflower blossoms were used in a number of religious ceremonies.  The blossoms also can be boiled to make a light tea – but, add a little honey.


The leaves can be eaten raw in a salad.  They can also be boiled or sautéed just like spinach.


Sunflower Summary

All in all, the whole plant – from top to bottom – can be consumed or utilized in some way or fashion.  And, the health benefits are extraordinary…

  • Proven to lower bad (LDL) cholesterol
  • Suspected to help weight loss
  • Promotes healthy bones
  • Smooths and softens skin and hair
  • Regulates blood sugar
  • Aids sleep
  • And more…

Interesting Tidbits

Van Gogh Sunflower painting

Sunflower heads follow the sun – looking East in the morning and West in the evening.  This is actually true only for immature heads.  Once the sunflower heads open up and mature, they will most likely remain pointed in a generally East direction.

Van Gogh produced a series of sunflower paintings – one of which was sold for a whopping $39.9 million dollars!


Sunflowers Are Oh, So Easy To Grow!

There are only TWO types of sunflowers that I will grow.  Are you curious to see what my special sunflowers are?

  • After the last frost, pick a sunny location with well-drained soil. Remember they are called “sunflowers” – they like lots and lots of sun – at least 8 hours or more, if possible.  Native American Indians would normally plant these as the fourth sister on the North side of their Three Sisters combination (i.e. corn, green beans, and squash).
  • Till the soil at least 6 inches deep and mix some of Jim’s 50/50 soil mixture into the soil
  • Plant a trio of seeds a half inch deep – spacing the other trios in the row about 2 feet apart. Keep the rows 2 feet apart.
  • Add a generous amount of compost around each trio – they love it! No compost prepared?  Then, liberally spread some organic mulch – and, it will begin composting on its own.
  • Keep everything moist, but not soggy wet, until the sprouts start to peek up out of the ground. It takes about a week and a half.
  • When the sprouts have several sets of leaves, thin the trios – keeping the strongest one in each spot.
  • Hold back the weeds by continuing to mulch around the plants. Don’t forget – weeds are the enemy of our garden crops.  They suck up all the water and nutrients – leaving nothing left for the real objects of our pride and joy!  Additionally, the mulch will help the soil stay moist and cooler during the hot summer months.  TIP:  Try to keep mulch away from the stalks as they may encourage root rot.

At the end of the growing season, completely remove sunflower plants from the garden area to keep from introducing plant diseases next year.


Time To Reap What You Have Sown

It takes roughly 3 months for sunflower heads to mature enough to be harvested.  Key signs of readiness are:

Sunflower head drooping

  • Stalks are getting dry.
  • Center florets are shriveled and turning brown.
  • The back of the flower head is turning from green to yellow to yellow-brown to dark brown.
  • The head is drooping.
  • The seeds are darkening in color and may be striped.
  • It’s getting to look a lot like summer is over and fall is on the way – a really good sign if you missed all the others.

If all indications of maturity are noted, cut off the heads about 6 inches below the flower head and hang them in a warm, dry, airy place for a few days to ensure that the seeds are fully ripe and dry.  Cover them with a light porous fabric to prevent birds and mice from getting at them.  The fabric will also prevent seeds from dropping off the head.

If it is very difficult to remove the seeds, then they are not dry enough.  Give them a few more days and try again.  They should be fairly easy to strip off the head.  TIP:  If the back of the head is dark brown, the seeds are surely dry enough to harvest.

Many gardeners I’ve talked with all have their very own “pet technique” for removing seeds from sunflower heads.

Using a washboard to remove sunflower seeds.

Some old timers just run their thumb over the head – peeling away the seeds as they go.  I tried this and got thumb blisters.  I guess they must have very leathery thumbs!

Others take an old washboard and just rub the head back and forth on it to loosen the seeds – or, they take an old stiff vegetable brush to the head.  I tried this – it works – but, I ended up with seeds all over the kitchen!

My own method consists simply of taking two sunflower heads and rubbing them together over a large colander.  Since that is where they will end up to be washed anyway – I am killing two birds with one stone.

After washing all the crud off the seeds, lay them out on a paper towel to completely dry.  Then, eat them raw – or roast them in an oven at 300o F (150o C) for about a half hour – and salt to taste.

TIP:  An easy way to crack the hulls of unshelled seeds is to place them in a plastic bag and roll over them with a rolling pin.


Sunflower Diseases

Fusarium is, more often than not, the main enemy of sunflowers.  It is fungi lurking in the soil and does the most damage to crops.

Downy mildew is another sunflower nemesis.

Daconil fungicide

The best way of dealing with these diseases is to hit them with a good dose of a fungicide, like Daconil, as soon as they show up.  If you’re too late, then you will have to completely remove the plant from the garden and either burn it or throw it in the garbage.  Do NOT put diseased plants in your compost pile – or, the diseases will end up back in your garden next year.


Pests That Love Sunflowers

Birds and squirrels go nuts over sunflower seeds.  When the heads get big and start to droop, cover them with a porous fabric to protect them.

Keep deer away with a wire fence or deer repellent.

Now, Here Comes Neighbor Jed

The other day, my neighbor, Jed, the retired farmer told me that, “…seein’ those purty sunflowers” in my garden reminded him of the time back on the farm when he was sittin’ on his tractor taking a lemonade break and admiring his beautiful sunflowers when some ambulances and police cars came roaring down the road.

Jed went on…

“When they saw me, they stopped and asked me if I had seen a busload of politicians that were in the area trying to get votes to win the election coming up next week.

I told them that, indeed, they had come down my road and their bus crashed and ended up in the gulley just over the hill.

Well, sir, they were a bit curious as to what happened to all them politicians and, I said that I buried them over next to my patch of sunflowers.

One of the policemen asked, ‘So, they were all dead then?’

I told him, ‘Some of them said that they were alive, but – you can’t believe anything a politician says – now, can you?’

And, that there bus is still perched in that gulley to this very day!”

Wrecked busload of politicians

I just can’t get enough of Jed and his stories.  Would you like to read more about Jed?

I also love my sunflower seeds.  How about you?  Most of us have eaten store-bought seeds but, have you every enjoyed the home-grown version?  I welcome hearing from you in the comments or by email.

    I enjoyed this article from beginning to end! Was just chock full of information on the sunflower! I like how you added Jed’s sunflower story to the end too, it was the perfect finishing touch. Also, I have to say, as an art lover, I also love that you put in Vincent Van Gogh and his sunflowers series. I never thought about eating the sunflower, I mean other than the seeds that is, which I love. I’ve been trying dandelion tea, maybe there is a sunflower tea. Wouldn’t have thought of it without this article though. Thanks! 🙂

      Thanks, for stopping by, Nikki.

      Jed is a real character – and a great neighbor!  He loves to recount stories and anecdotes – which gives me a much needed break from gardening activities.  It’s interesting, though – he always seems to come by when I have just started working on a new batch of ice cold lemonade!

      It is truly wondrous when you learn how many parts of our plants are edible – even the sunflowers.  I throw away very few plant parts.  If I don’t eat them, they end up in my compost pile.

      Take care,
