Sunflowers (Helianthus annuus) have an inherently happy disposition with charming heads that follow the sun. They’re also quite handy for constructing houses, forts, walls and mazes for kids. These flower homes become the perfect place to bring kids and nature together in some of the most imaginative ways. Sunflower structures are visited by butterflies galore and the largest sunflower varieties grow leaves and flowers larger than your kid’s head! Sunflower houses are a wonderful way to get your kids into the garden.


You’ll want to plant the big-to-monster size variety as the main support:

  • Mammoth Gray Stripe- 8-10 feet tall with 15-20 inch flower heads

You can use other varieties of sunflower in between the stalks for color variation and for filing in:

  • Velvet Queen- 4-6 feet tall with 6 inch flowers
  • Autumn Beauty- 5-6 feet tall with 5 inch flowers
  • Red Sun- 4-5 feet tall with 3-4 inch flowers
  • Vanilla Ice- 4-7 feet tall with 5-7 inch flowers
  • Orange Sun- 4-5 feet tall with double flowers
  • Peach Passion- 3-4 feet tall with 3-4 inch flowers

Of course, you may want to embellish your sunflower house at knee-level with the shorter varieties such as:

  • Irish Eyes- 2-3 feet tall
  • Junior- 1-2 feet tall with 4 inch flowers
  • Dwarf Sunspot- 2-3 feet tall with 10 inch flowers
  • Elf 1-2 feet tall

The last couple of things you’ll need are Scarlet Runner Bean Seeds, like my favorite, Scarlet Emperor, and a big roll of twine, jute, or very light rope.

Build a Sunflower House:

The first thing you need to do is choose the site to plant the sunflower house. This area needs to get 6-8 hours of sun during the day. Sunflowers are at their best in brilliant sunshine. So, the more sun the better. Most people plant a rectangle-shaped structure. Feel free to make whatever size house your kids would like or your yard can hold. To get as much light as you can on your sunflower house, you\’ll want one of the short rectangular ends facing north. This step isn’t going to make or break your house, but its the way to get the most benefit from the daylight.

One thing that’s important to know about sunflowers, especially if you’re trying to get them to a giant size is that they’re very heavy feeders – much like corn. So when you first sow your seeds, make a 5 or 6 inch trench along each side of the house and fill it in well with compost or composted manure before planting the seeds. A little fertilizer while the plants are actively growing wouldn’t hurt, either. The rule of thumb with seed planting is to plant it twice as deep as the seed size. It’s the same with sunflowers. This is an easy first rule for kids to remember and sunflower seeds are the perfect size for small fingers to handle.

Plant the giant sunflower seeds first at about 6 inches apart, filling in behind or in front of those seeds, the medium size sunflowers and finally, the little guys. There’s no specific strategy when building your house other than to have the whole thing in a basic rectangular shape. Otherwise, you and kid’s sunflower house is suppose to be unique. Don’t forget to leave a few feet of space unplanted at one of the shorter ends to create a front door.

Plant the Scarlet Runner Bean seeds at the base of the sunflowers along the two longest sides of the house. The bean plants will now grow up the sunflower stalks.

The center (inside) of the house should have straw, grass, or some other material that’s pleasant for feet as this is the floor of your house. Keep the trenches evenly watered and as the bigger sunflowers grow, they may need some support such as stakes. The medium-sized flowers will be supported by the giants. When the sunflowers are reaching their mature height, take the twine or jute and tie it on to the first sunflower just below the flower head. Then weave the twine throughout the top of the entire structure – making sure to go across the entire open space -like you’re attempting to sew the top together.

The idea here isn’t to pull on the flower heads, but rather to make sure it’s taught across the top of the sunflower house. When the bean plants reach the top of the sunflowers, they’ll begin to grow out onto the twine and make a beautiful green and red ceiling. Don’t let the kids keep the magic for themselves. When the beans begin blooming, get into that sunflower house, lie on your back and admire the green and red that you and your kids planted.

Using the same basic technique and have kids come up with their own idea for sunflower structures such as for walls (forts) and even backyard mazes – which for some zones could still be intact for October and can then be modified with pumpkins and gourds as a Halloween maze.

  • So glad you’re doing a sunflower house. I wrote Sunflower Houses in 1991 and since then have rieceved hundreds of letters and photos of beautiful creations. Sometimes nature hurls everything at us, but just having one sunflower is enough for JOY! Keep up your great Mother’s work and blog (when do you find time). I so enjoy it.Please visit my blog. I’m going to have a drawing in a few days for some of my books and others.Green Blessings,Sharon Lovejoy (
