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.

SO WORTH THE PRICE
Color: Pink, Size: Queen(20"X 30")
I bought these in two colors for my new apartment with some new pillows to go on them because I got a whole new set of sheets and comforter for my bed and I have to say these are some of the softest most comfortable cooling pillow cases ever! The silk is not super great quality but for the price it's totally worth it I've noticed that it takes care of my hair better I never used silk pillow cases before... But I don't think I'll ever go back. And the zip closed with a zipper so they stay on your pillow no problem without sliding around and you having to fix them all the time they're so easy to use and they look perfect. They look exactly like the pictures! Definitely worth the price... Oh, and there's no weird smell or anything these are definitely good quality!

Helps hair health.
Color: Lavender, Size: Queen(20"X 30")
Amazingly soft, cool and comfortable. The sizes are accurate so fit pillows easily. We mixed two colors so our bed looks as comfy and inviting with stylish color blending. Hair seems happy!

These give the benefits of a silk pillowcase on a budget.
Color: White, Size: Standard(20"X 26")
These are very nice pillowcases. Are these made from mulberry silk? I’d have to say no based on the burn test. However if anyone thinks they’re going to get a real mulberry silk pillowcase for this price, they need a reality check. I’ve purchased authentic mulberry silk pillowcases online from between $45 and $105. Most are $70 and up. I’ve bought a number of so called silk pillowcases up to $25. The Infiixso pillowcases are probably the nicest of this latter group. They have the right amount of sheen and the right amount of slip to them. They are very soft and went through the wash well in a mesh bag. I did put them in the dryer and meant to take them out after ten minutes but forgot them; taking them out after about 20 minutes on medium heat. One was a little wrinkly but it was in the mesh bag still. The other one came out fine. These fit my pillows without issue. The zipper seems to be sewn in well. The white is a true crisp white. These sleep cool and my hair glides across them so my hair looks better in the morning than if using a regular non-silk pillowcase.

RECOMMEND
Color: White, Size: 2 Pack Standard(20"X 26")
Warning: if you buy the color black, it will bleed and stain your pillows. This happened to me. I had to throw out my pillows. This issue does not sway my rating. The pillowcase is wrinkle-free and super soft. Fits standard-size and queen-size pillows. Quality and appearance are excellent. After my unfortunate purchase of the black pillowcases, I purchased the white, and I’m very happy I did. I gave a 5-star rating because they are beautiful and of great quality.

LOVE this silk pillowcase!
Color: Cream, Size: Queen(20"X 30")
I have been wanting a silk pillowcase for awhile but wasn't sure if I would like sleeping on one. Much to my delight, I LOVE sleeping on a silk pillowcase and this one is quite nice. First- I love that it fit my oversized pillow. I ordered a queen size and I had some room to spare without it being overly big. I also love that it has a zipper close so the pillow case stays on well and doesn't move around too much. I washed it before using and let it air dry and the pillow case didn't have any wrinkles which is wonderful. It stays cool to sleep on and my skin and hair love it! Very comfortable, great value and lovely design!
