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.

Disappointed.
Color: Blue, Size: Large, Color: Blue, Size: Large
This sweater is so comfortable and very soft. It fits well in a flattering, oversized way. But after one wash it is pilled everywhere which makes it look old and shabby. It’s at a price point where I feel compelled to return it.

Perfect for casual wear and dressy style
Color: Dark Green, Size: Small
This sweater is soooo soft and the color is so rich. The fit of it is perfect, not too tight and not too baggy, just right and I used the size guide to pick my size. Just for reference, I am 5'3" and 130lbs, 38C bust. It's well made and washes great. I chose to hang dry mine as I typically don't put any of my sweaters in the dryer to dry, just to fluff them. I have this one in two colors, the green and the tan/beige and I would say they are both a true representative of the color shown.

Love the long sleeves!!!
Color: White, Size: Small
Love it! I'm 5' 11" tall and I purchased this according to reviews. Several people commented on the length of the sleeves. I have a hard time finding sleeves long enough if it's not " tall" sized. It was perfect for me. If this washes nice I'm going to consider purchasing more in other colors. I ordered the white and just love the long ribbed cuffs with the line of buttons. Very soft.

Nice cozy sweater, but handwashing is recommended
Color: Beige, Size: Medium
Soft and cozy, but does not wash well. Goes with everything. This sweater fits well and looks great. I received lots of compliments while wearing it.

Great sweater for winters in the Midwest
Color: Black, Size: X-Large
Love this sweater! I went back and got another color! The fit is true to size and very comfy. The button detail on the sleeves just adds a little pizazz. The weight of the sweater is perfect for winters in the Midwest.
