Mammoth Sunflower Seeds


Mammoth sunflower seeds NON GMO, 100% ORGANIC - Organically grown on our farm- READY for planting! USA Shipping ONLY


These wonderful seeds have a HIGH germination rate. All plants were hand grown organically right here on our farm, then hand picked once ready.  Sunflowers make a beautiful addition to your garden, a wonderful living sunflower hut hideout for your kiddos to play in, or a great garden wall.  All while growing delicious edible seeds for you and all your bird friends. The dried heads make great decorations for your thanksgiving table, not to mention perfect hanging bird feeders!

Can be sown indoors 2-3 weeks before planting outdoors. Transplant when there are 4 leaves.
Expect germination in 5-10 days
They are best sown outdoors after last frost, but remember animals WILL eat the seeds if they can get to them.

When sowing seed outdoors, we recommend a planting depth of 1 inch

Spacing: Plant or thin to 12 to 24 inches apart in full sun ( the bigger the space, the bigger the seed head will be). They will be 5ft to 12ft tall at maturity


Soil: Very tolerant of drought and poor soils


Temperature: Grown best between 75 to 90 degree days 


Water: Water everyday until sprout is 1 foot tall, then move to watering every other day. once fully established, watering twice a week in temps 70 -80 is ok. In temps hotter, water every other day. Sunflowers will do fine with minimal water but NOT soggy soil. 


ALL our seeds are grown, loved and harvested directly on our farm! Because we are a small farm with limited room, we do grow LOTS of varieties of sunflowers which increases the risk of cross pollination. Due to this, the seeds you grow may come up a slight different color or size than expected.
We do our very very best to remove all extra matter( leaves, petals, etc..) but being they are untreated, unwashed, and harvested by hands there may be a couple tag along pieces. But its OK, just extra compost for your garden bed!! 




PLEASE READ.. all seeds are fresh and viable. We will not be responsible for the germination of any seed since everyone has their own methods of starting, growing and planting them. We will only give you the advice that we believe works best.
