Mammoth Sunflower Seeds – Heirloom, Non-GMO, Non-Hybrid, Open-Pollinated

Grow towering Mammoth Sunflowers with our premium, heirloom, non-GMO, non-hybrid, and open-pollinated seeds!

Perfect for attracting pollinators, creating a beautiful garden backdrop, or harvesting delicious sunflower seeds for snacking or feeding birds.

Each packet contains 8g of seed, approximately 125 seeds.

Planting & Growing Instructions:

Days to Maturity: 75–90 days

Planting Depth: 1 inch

Plant Spacing: 18–24 inches apart in rows spaced 2–3 feet apart for best growth.

Days to Germination: 7–10 days with soil temperatures of 70–85°F.

Sun or Shade: Full sun is essential for optimal growth and large blooms.

For best results, sow seeds directly outdoors in well-drained soil after the last frost. Mammoth sunflowers thrive in warm weather and benefit from being planted in a sunny, wind-protected location. While starting seeds indoors is possible 2–3 weeks before the last frost, these vigorous growers prefer minimal transplanting. Once established, water regularly, especially during dry periods, to support their rapid growth and large flower development.

Ideal for gardeners of all skill levels, Mammoth Sunflowers add natural beauty, provide edible seeds, and help sustain local pollinators. Our high-quality seeds ensure reliability, making them a must-have for any garden project. Shop today and bring these iconic giants to your garden!

Large is a little big for Bostons
Color: Dogwood (Brown), Size: Large (Pack of 1)
Seems to be durable for 2 VERY agressive chewer Boston Terriers. Cricket and Alice are shockingly good at chewing - grateful they pick to do so with thier toys. Trial vs other name brand competitor. PetStages' is a little larger so harder to bite on fir small dogs, but seems to be equally durable. While PetStages proudly states it has real wood fiber and scent (whoch I thought would win)... they prefered the other. Both dogs love to chew on real sticks. But, when the bossy one indicated she was taking over the stick the other dog had, they exchanged, and kept chewing, over and over, back and forth. I mean to say, whatever the prefered stick was at first didnt seem to matter later. These super hard chew toys do make me nervous. One dog broke a tooth last summer on a different brand toy, a very expensive extraction bill, and poor pup's terrible discomfort... but the other did not and has amazing white teeth, all around.... so.

The best chew ever for a strong chewer
Color: Dogwood (Brown), Size: Large (Pack of 1)
We have a 77lb goldendoodle who loves these. We’re lucky because he doesn’t chew on anything other than his toys, but when he starts on this…he really goes at it. It’s healthy, (not synthetic), doesn’t break apart, (no pieces to worry about him swallowing), it just perfect for him. The noise may get on your nerves but it’s a small price to pay to keep him from chewing on your furniture, shoes, or anything else a mischievous dog can find.

Little pieces break off
Color: Dogwood (Brown), Size: Large (Pack of 1)
My dog is obsessed with this. It does last a long time even given her strong chewing capabilities. I wish it was a little bigger. The main reason I rated it so low is when my dog is chewing on this it breaks off a little plastic peice and sometimes it hits the back of her throat making her cough so you have to supervise with this.

Great for aggressive chewers
Color: Dogwood (Brown), Size: Large (Pack of 1)
My dog is an aggressive chewer so they are great for her. I would love to have one a bit thinner so it could fit in a holder so it is easier for her to hold while eating. This keeps her busy and is long lasting. I have purchased these multiple times.
