Sowing Instructions

DIRECT SOW IN FULL SUN WHEN SOIL TEMPS ARE ABOVE 60°F

Starting Indoors

6-10 WEEKS BEFORE LAST FROST

Growing Tips

Direct sow your seeds in the garden when soil temperatures are between 60-70°F. Transplant from indoor starts when soil temperatures are around 70°F. Plant multiple seeds outdoors or in each cell (indoor starting) and thin to the most successful plants.

We tend to plant Sunflowers at random without thinning and allow them to establish on their own without intervention.

Culinary Uses

Mammoth Grey Sunflowers are known for their large heads and numerous seeds. The seeds harvested are usually roasted, salted and eaten as a snack. Birds also love sunflower seeds, so do not be surprised to see them stealing your seed crop.

Harvesting Seed

Harvesting sunflower seeds can be fun for everyone. Wait until the sunflower petals start to wilt and fall off the sunflower head. The head should start to become dry and brown and may even start to fall over.

Once the heads start to become brown, place a paper bag upside-down over the head of the sunflower. (This protects your seeds from birds and squirrels).

Check your sunflower heads daily to see if the seeds have become hard. Once the seeds are hard enough to harvest, cut the stem of the flower and hang it upside down to dry thoroughly. Once the heads and seeds have dried enough, running your hands back and forth over the seeds will release them.

Roast your seeds as a snack or save them for next years harvest. (We recommend saving your seeds from the first harvest to produce hundreds of plants the next year)

The most amazing blanket EVER!!!
I just got this yesterday and I’m obsessed already. It’s the softest thing I’ve ever touched. The reverse side is also a super soft velour-like feel. I got the Marble Charcoal Grey in 60x80. It looks exactly like the photos and it’s truly a bubble design too. Looks so good draped across my bed. And it’s HEAVY! Literally feels like a weighted blanket on top of being unbelievably soft and cozy. Now I want to get the largest size for even more heavy, snuggly bliss. I slept with it last night along with my normal blanket and I fell asleep much quicker than usual. It does shed a bit on my black clothes but I don’t even care lol. The packaging it arrives in makes it wonderfully gift-able and also lets you know it’s a women-owned company. Didn’t arrive with any bad smells either. All the stitching is immaculate, really everything about this blanket is. I got it on a Black Friday deal for $20% off at $51, it’s worth every penny and feels like a steal to be honest. The quality is unmatched. I’ll have to refrain from buying every single color!

Worth every penny
Color: Ivory White, Size: 90"x90"
This blanket is so soft and comforting, I just love it! It arrived sealed in a plastic bag and fluffed up instantly, I briefly put it in the dryer on low and it came out absolutely perfect. There was no odd smell, no loose threads, it was very well made and looks so inviting on my bed! Definitely a great buy that will keep you warm.

A warm hug from this fantastic blanket!
Color: Cream, Size: Throw(50" X 60")
This is my go to blanket when I want to cozy up on the couch. So soft and warm, it’s like snuggling a hug! Washes well and lasts forever years. I replaced mine after 4 years with the same thing in a different color option! Perfect size to cover up and also a nice accent piece on the back of the couch.
