Grow Sunflowers In Your Yard Or Garden

A beautiful and fun flower to grow is the sunflower.  They got their name because the colorful blossoms will turn during the day to follow the sun's path.  Although most people think of them as yellow, there are actually several varieties that aren't yellow at all.

Along with having the lovely flowers (just one or two in a tall vase can be spectacular) you can also grow sunflowers for their delicious and nutritious seeds!  You can harvest these to eat yourself or save them for a mid-winter treat for birds in your yard. 


Colors and Types of Sunflowers

Although most people would presume that sunflowers are yellow, there are actually quite a few color variations available.

  • Yellow - These can be dark gold to bright lemon yellow.
  • Red - The red range can go from dusky orange or rust to bright cherry red.
  • Green - Sometimes called lime or ice green.
  • Chocolate - This is the name give to brown sunflowers.
  • White - A very pale flower.

The petals on a sunflower can vary as well. Some have bold, spaced petals while others like the Teddy Bear sunflower are covered with so many little petals, they look fuzzy! You will also find varigated sunflowers, where the petals fade from one color to another, or into several more. These can be quite dramatic.

Not all sunflowers grow singluarly either. While some stalks are topped by just one large bloom, some variations put out multiple flowers all along the strong stems.

If you get a seed mix, you'll have the ability to grow different types and be surprised all summer!

Hybrid vs Heirloom

  • Hybrid varieties are purposeful crosses of two plants, and those seeds will not reproduce themselves. The offspring will show characteristics of one or the other parents. They must be repurchased fresh each year
  • Heirloom or open-pollination varieties are plants that will produce the same type of flower if the seeds are saved until the next year. These are favored by organic and permaculture gardeners.


Planting Sunflowers

Start by finding a spot in your yard or garden that is 1) sunny and 2) has room for plants that can be five feet tall or taller. Sunflower definitely grow best where there's lots of daytime sunshine and you want to make sure they aren't going to bump into anything when they reach their full height, or shade out other plants below them that might also need some sun.


Growing sunflower plants need plenty of water, especially if the plants are young transplants or if the weather is hot for a sustained amount of days in a row. Giant-head varieties and other "super" seed producers may also need poles for extra support or to ensure sturdy growth. Be sure to tie stems to supports with soft ties so as not to damage plants. They also benefit from being fertilized. (please use only organic products for your benefit and that of the critters in your yard!)

Saving and Drying Your Sunflower Heads

As sunflower heads approach maturity, it may be necessary to protect developing seeds from birds, squirrels or other garden nibblers. Netting or bagging the heads can guard the seeds before they fully loosen or start being eaten. Cheese cloth or small paper bags are most often used. One really easy method is to use a small-mesh lingerie bag which can just zip closed around the stem but still let plenty of air to the flower head.

One interesting thing about sunflowers is that while they are developing, the heads will turn to follow the sun, BUT once the seeds really start to grow, the sunflower will stay facing to the east to protect them from the serious sun rays that come from facing west.

How to Tell When The Sunflower Heads Are Ready For Harvest

  • Watch for the back of the seed head to turn from green to yellow. When it gets really yellow, you'll want to cut the head and as much stem as you can from the plant. Then take the head and hang it up in a dark, dry location to finish drying. How much time that takes will vary. You'll know when the seeds are done as ripe seeds will be lose in the head and should be able to be brushed out by hand easily.

Uses for Sunflower Seeds

Roasting Sunflower Seeds

  • Boil the seeds (shells and all) in heavily salted water for about an hour, and then roast for about 20-30 minutes in an oven that's about 350 degrees. Keep an eye on those seeds after the 20 minute mark as you want them roasted and not burnt, and how long they take will vary slightly with each batch you roast.

Sunflower Seed Butter

  • Shell (hull) your seeds and then crush them with a mortar and pestle or run them through your food processor the same way you would with any other seed or nut.

Saving Heads For The Birds

  • Many people who grow sunflowers for the birds pick and dry the heads, offering them later in the winter. Leave a good amount of stem on the head when you dry it, and it will make it easy to hang as a bird feeder all by itself!

one thought - make SURE that the back of the sunflower face is really yellow, and nearly dried out. I made the mistake of taking one off too early, I hung it, as suggested, but it was too wet yet, and it molded. I lost most of the seeds to rot.

Actually Marilyn, there are a whole lot of plants that don't transplant well and that's why you grow those seedlings in peat or some other appropriate pot that biodegrades and you plant the entire pot and the seedling. It works like a charm.

Great article on sunflowers but I don't recommend anyone start them as seedlings inside and then transplant them. Sunflowers don't take to transplanting well. I have done it but had several plants die and most of the rest aren't what I would consider strong growers.

Last year I just had one plant, which I got as a start at the Farmer's Market. I saved some seeds from it, and I'm about to start those indoors to see if I can get a whole bunch growing this year.

This is a very well written and informative hub with some really good tips.

I am really fortunate in that I live in the South of France and the local farmer plants a whole field full of Turnesols right in front of my house (usually every other year) so I get to enjoy the beauty of them without any of the work.

I grow sunflowers in my garden every year. I love watching the birds and the squirrels nibbling on the seed heads. Its like having your own nature channel in your back yard!

Jerilee, a farmer who has a huge field can afford the loss of some of the crop to birds, but for a backyard gardener with just a few plants, protecting heads really makes a lot of sense so that you actually get some seeds.

I'd never heard of using a protector from the birds, very cool idea.
