Grow towering, show-stopping blooms with Mammoth Sunflower Seeds, a classic heirloom non-GMO variety that combines ornamental beauty with practical harvest value. These single-stem giants reach 10–12 feet tall, producing massive golden-yellow flower heads up to 12 inches wide—a true centerpiece in any garden.

Beautiful and Productive Giants:

  • Grows 10–12 ft tall with strong, sturdy stalks.
  • Produces large flower heads packed with hundreds of oil-rich, edible seeds.
  • Ideal for roasting, snacking, bird feed, or seed saving for next season.
  • Excellent for pollinator support, wildlife feeding, or use as a natural privacy screen.

Why Gardeners Love Mammoth Sunflowers:

  • Classic Giant Variety – A traditional favorite for its height, size, and yield.
  • High-Yield Seed Harvest – Produces plump, nutritious seeds for humans and wildlife alike.
  • Bold Garden Focal Point – Bright golden blooms command attention in borders or homestead gardens.
  • Easy & Reliable Growth – Thrives in full sun and well-drained soil across USDA Zones 3–11.
  • Drought Tolerant – Strong, deep roots make it a resilient choice for summer heat.

How to Grow Mammoth Sunflowers:

  • When to Plant: Sow seeds directly outdoors after the last frost when soil has warmed to 60°F (16°C) or higher.
  • Soil & Sun: Prefers well-drained soil and full sun; amend with compost for best growth.
  • Spacing: Allow 18–24 inches between plants to give stalks room to grow tall and strong.
  • Watering: Water deeply once or twice a week to promote deep root systems.
  • Bloom & Harvest: Expect blooms mid-summer, with seed heads maturing late summer through early fall.

Harvest & Use:
After petals fade, let heads dry naturally on the stalk until seeds loosen easily. Harvest and roast seeds for snacking, save for next year’s planting, or leave them out for birds and pollinators to enjoy. With its towering presence and generous yield, Mammoth Sunflower is a must-have for gardeners seeking both impact and sustainability.

Bad Product
Size: 20oz
There was no pressure in the can. It would not even inflate a bicycle tire. Be careful there is no amazon refund or return with this item!

IT WORKS, IT REALLY WORKS!
Size: 16oz, Size: 16oz
I carry a tire plug kit in my van. Low pressure light came on and quickly made my way to air pump. Checked out tire and was at least a 5/16" bolt right between tread, very easy to locate (hissing). Inflated tire, prepared plug, pulled out bolt, inserted plug done. Almost home light came on again. Used water soap and plug was still leaking. Tried double plug and still leaking, but would take days to trigger low pressure light. Tire still had decent tread and didn't have facilities to patch, so got a can of fix a flat. I have never believed in this stuff, but it worked. No low pressure warnings for about a month. Around here they would charge $50 for a patch, 2 .25 cent soft rubber plugs and fix a flat, problem resolved!

Buy it! Lifesaver!
Size: 16oz
Yes, buy it when you don't have a spare tire because you will need it! I live in Florida and flat tires are just part of living here! Saved my life twice already and is absolutely self explaining! Cheaper then a spare tire, lighter than one too! Just throw it in your trunk and best case you will never need it but just in case!

Difficult to use and eventually hose end broke
Size: 24oz, Size: 24oz
I purchased this can of Fix-A-Flat to fix, what I believe, is a rim leak on my truck tire which needs to be filled once every week or so. When I attempted to use the product I let some air out of the tire (down to 25 psi) so it would be easier to dispense the contents. The instructions on the can say to have the valve on the tire at the 6 o'clock...which I did as well. When I attempted to make the connection using the swivel connector on the can's hose it was difficult. The hose on the can is very short and stiff and because it came coiled in the can's lid, did not want to straighten out making connecting it to the tire a very awkward process. It was hard to screw the hose end on the valve without it binding so it felt like it was cross-threading. I have machined aluminum valve caps and they go one very easily so I know the threads on the tire's valve stem are clean. I finally did get it on and when I attempted to dispense the contents it filled the hose but that was about it. I could not see any contents flowing thru the hose at all. I assumed it was not on far enough so I took it off to try again and the contents sprayed everywhere showing it was indeed under pressure....just not going into the tire. After multiple tries the hose end eventually just broke off and stayed on the tire's valve stem. I was able to get it off, but at this point the can is useless to me. Obviously I cannot and will not recommend this product. I have used this product before and had success, but that was when the hose was longer and wired to the side of the can making it much easier to use, versus how they are shipped now. I would recommend going with another product or possible going to a box store (which is what I plan to do) to find one that does not have this design. At the very least, if you do choose to disregard this review, I would try it with the tire's valve stem at the 3 or 9 o'clock position which might make it easier to thread the hose end on to the valve stem,. Also, if you choose to go this route you might just be throwing your money away. I attempted to get a refund from Amazon and was directed to the manufacture's web site. From there you are directed to use the 800 number of leave a general message that is in no way connected to your Amazon purchase. Past experience tells me it will not be an easy process so it looks like I am out the $12.
