Learn everything you need to know about growing sunflowers from seed with my YouTube video tutorial: https://youtu.be/CPne6yt5uTI

This is one of the tallest sunflower varieties in the world. Huge 9 to 12 foot stalks adorn bright and sunny blooms that are around 1 foot in diameter. Each stalk typically produces one bloom. They start blooming at about 3 months from seed. Each head will produce a ton of seeds for human and bird consumption. After blooming, the stalks and leaves offer a lot of biomass to be used for composting or mulching. 

Follow me on social media because I talk a lot about the same seed varieties I sell here in my shop and gardening tips. IG, YT, and TikTok: jerrasgarden.

Terms and conditions READ THIS PLEASE:
- Seeds will be shipped with no planting instructions to keep seed costs low to the buyer. Germination and plant care information is included in the description. I encourage each gardener to research specifics on how to be successful growing them. I also have lots of information on my TikTok, Instagram and YouTube channel all under the account name jerrasgarden. I started this shop to share my love of certain seed varieties and spread the knowledge of gardening. Please contact me if you cant find information or have additional questions.


- No returns or refunds once shipped. I am not responsible for lost or damaged packages caused by USPS. Since there are so many factors that affect germination and growing success, no refunds or exchanges are allowed once seeds have shipped. These are the same seeds I use in my personal garden so I can attest to their viability. Seeds are fresh season to season.


- Availability of seed in this shop varies depending on what I have decided to grow that season. With that said, please be advised that seeds are available in limited quantities. Once sold out they may or may not be available again.
