Sea Island Cotton Seeds | Egyptian Cotton | (Gossypium barbadense)
The finest cotton in the world. A remarkable plant with an extraordinary history.
Gossypium barbadense, Sea Island Cotton, is the long-staple cotton species that produced the most valuable and sought-after textile fiber in history, cultivated on the Sea Islands of South Carolina and Georgia from the 1790s and commanding prices two to three times higher than upland cotton because of its extraordinary silky fiber length and strength. It is a beautiful tropical plant with large yellow flowers marked with deep purple centers that age to pink and rose, ornamental by any measure, and produces the cotton bolls filled with the exceptionally long, lustrous fibers that made it the most prized raw material in the textile industry for over a century. If you are looking to buy Sea Island Cotton seeds or grow this historically significant plant, this is a textile and ornamental plant with one of the most compelling stories in American agricultural history.

Things you probably did not know about Sea Island Cotton
Sea Island Cotton made a small group of South Carolina and Georgia planters the wealthiest people in North America. At its peak in the early 19th century, Sea Island Cotton sold for prices that made its producers extraordinarily rich by the standards of the time. The per-pound value of Sea Island Cotton fiber exceeded that of gold by weight in premium years. The entire economy of the South Carolina and Georgia Sea Islands was built on it.
The Egyptian cotton you buy at department stores is a descendant of Sea Island Cotton. Egyptian long-staple cotton, marketed today as the premium cotton for bedsheets and luxury textiles, is largely derived from Gossypium barbadense varieties developed from Sea Island Cotton genetics. The long, silky fiber that makes Egyptian cotton sheets feel distinctive traces back to the same species grown on the South Carolina coast two centuries ago.
The Civil War destroyed the Sea Island Cotton industry. Union forces occupied the Sea Islands early in the Civil War and the enslaved population that had maintained the crop was emancipated. The specific knowledge, techniques, and labor organization required to grow and process Sea Island Cotton was dispersed and never reassembled at scale. The industry never fully recovered. Within a few decades the Sea Islands had shifted to other crops and the dominance of Sea Island Cotton in the global textile market was over.
The purple center of the flower serves as a nectar guide for pollinators. The deep purple-maroon center of the Sea Island Cotton flower is precisely located at the entrance to the nectary, guiding bees and other pollinators to the pollen and nectar source. The color is visible in both the human visual spectrum and in the ultraviolet range that bees see, making it twice as effective as a directional signal.

FAQ
FAQ
Do you pre-stratify the seeds?
Most of our seeds are not pre-stratified. We ship them unstratified so you can control germination timing based on your local growing season. We sell to all 50 U.S. states and Canadian provinces, and since each region has different planting windows, pre-stratifying would risk seeds germinating in transit or before you're ready to plant.
True stratification requires cold, moist conditions, which can lead to premature sprouting or mold if not timed properly. To avoid this, we store most seeds in dry cold conditions to preserve viability — but this does not initiate stratification.
Do any of your seeds need to stay moist? (Recalcitrant seeds)
Yes — some species we offer are recalcitrant, meaning they must remain moist to stay viable and cannot be dried out. Examples include: Chestnut, Hazelnut, Paw Paw, etc.
These seeds are shipped in moist cold storage and are clearly labeled on the product page when applicable. Please refrigerate immediately upon arrival and follow included care instructions.
Do you ship internationally?
We currently ship to the United States and Canada only. Unfortunately, we cannot ship to other countries without a phytosanitary certificate, which is required by most international customs agencies.
If you're interested in shipping outside North America, please contact us. Note that a phytosanitary certificate typically adds $60–$80 USD per seed type and must be arranged in advance.
