9 Best Sustainable Seed Company Purveyors Of Plant-astic Bounty

Molly Willows

Dropped in dirt, blanketed by darkness, and reaching for the light. 

It’s not a metaphor for life: the intelligence, resilience, and magic alchemy of seeds is undeniable.

Choosing a sustainable seed company is vital for sustainable gardening, as they dig us out of the chemical-soaked genetically modified muck Monsanto (and all Big Ag) have buried modern agriculture in.

Fortunately, there’s a real garden variety of ethical seed companies providing organic, heirloom, and open-pollinated seeds, while vying for land regeneration, biodiversity, food sovereignty, and farmer’s empowerment.

Everything we recommend to you on Sustainable Jungle is independently researched and we ask all brands to confirm their claims. To avoid waste, we test products on an as needed basis.

Sustainable Seed Brands That Are Anything But Seedy

Your garden’s open pollination will be un-bee-lievable thanks to High Mowing Organic Seeds‘ highly reputed organic-only seed offerings—of which they donate over 100,000 packets a year to charitable and educational organizations.

Eco gardeners should take interest in Botanical Interests for the absolutely radishing bounty their wide range of non-GMO, organic, heirloom and sustainable gardening seeds offer.

Everything for bloom from Fedco is ethically sourced, non-GMO, and of the highest quality, which is why their sustainable seed company reviews are as bright as a fresh perennial harvest. 

When it comes to our own backyard homestead, you can bet that in any given year, the majority of our plants started from Fedco seeds (or our own saved seeds from the previous gardening season.

Every year, we look forward to thumbing through the pages of their adorably old time-y sustainable seed company catalog, which includes quirky sketches on its newsprint pages—meaning you can also recycle or compost it, unlike color or coated catalogs.

Likewise, the seed packets themselves are minimally-printed plain paper.

Their organic Cherokee Purple Tomato has a place in our garden every year, with lovely dark flesh that hides hand-down the most flavorful tomato flesh we’ve ever tasted. Summer caprese salad, here we come!

And for those who share in our zone 5a struggles, know that because Fedco is based in Maine, their seed stock is mostly cold-weather tolerant and ideal for shorter growing seasons.

Everything they sell is non-GMO and they have a robust offering of both hardy (and hearty) organic and heirloom seed varieties.

They source from individuals and small farmer co-ops as much as possible, always paying breeder and indigenous royalties to communities from which their seeds originate, as all companies should but sadly don’t. 

For varieties that originated in Africa, 10% of the proceeds go to the Northeast Farmers of Color Land Trust to help farmers of color purchase their own farms.

Plus, nothing is patented here folks, because Free the Seed!

Why Choose Sustainable Seeds?

Modern agriculture is not only one of the biggest contributors to climate change, it’s also responsible for the devastating loss of a whopping 90% of our crop diversity. 

In only fifty years, the proliferation of industrial agriculture led farmers down a dark trail of monoculture, mechanized farms, and GMOs which typically result in one crop grown abundantly… at the cost of the ecosystem’s wellbeing and the farmer’s sovereignty. 

This commercialization of agriculture has also meant complete dependence on large corporations for all aspects of farms, including seeds, which is perhaps at the root of our planet’s current biodiversity emergency.

Big Agriculture’s harrowing impacts hurt our collective health, environment, and food security.


Even farmers who commit to non-GMO seeds often have issues, since “pollen drift” from a farm neighbor’s GMO crops can result in the presence of GMOs in a neighboring garden’s non-GMO crops. 

Then when those seeds get saved and planted the next year, the gardener may unknowingly plant some version of a genetically modified crop.

Even more rotten is the fact that in the US today, a staggering 90% of all farmland grows genetically modified crops. 

For these reasons, we say make like a tree and leave the GMO seeds and chemical outputs behind.

Sustainable seeds are vital to a varied, strong gene pool and a natural ecosystem cycle, literally seeded with the task of ecosystem optimization. 

That means these seeds will attract pollinators, sequester carbon by way of regenerative agriculture, produce oxygen and crops maximally, water, cycle, and then repeat for a healthy, thriving, and more resilient ecosystem—and thus food system.

The thyme is ripe for sustainable seed company growth.

How We Choose The Best Sustainable Seeds Company

Why soil our gardens with chemicals and GMO plant varieties, when we can return our backyards to as nature intended? 

Sustainable seeds are crucial to regenerative and ecological gardening, which means choosing seeds that not only encourage more fruitful garden yields, but also increase biodiversity and a healthy plant ecology.

Here was our main criteria for choosing the best seed suppliers:


This is non-negotiable for us. We want to see zero biotechnology use to create genetically modified organisms.


Pollination is by outside forces like bees, bats, wind, or water, as opposed to farmers or scientists. Open pollination leads to “true to seed” plants, meaning you can save seeds to grow next season. 

GMOs and hybrids often won’t even produce seeds, or they don’t produce properly, making them by definition unsustainable.


USDA Organic credibility debates aside, to be organic, crops must be raised and processed in accordance with the USDA’s National Organic Program or a verified third-party auditor. Synthetic fertilizers and pesticides, GMOs, sewage sludge, and fresh manure are prohibited. 

It’s worth noting that this is not a hard-and-fast rule, as seeds can be sustainable but not organic (and vica versa). Heirlooms are a good example, as many heirlooms varieties come from small independent communities and growers that aren’t organically certified, but still use sustainable practices to preserve heritage seeds.


A pre-WW2 plant passed from one generation to the next and grown and saved for its hardiness, adaptability, flavor, and productivity. Heirloom seeds grow “true to seed” and are as close to the “original” seed that we have. 

Again, not all sustainable seeds are necessarily heirloom, but heirlooms are a safe bet on no contamination of the gene pool.

Any truly ethical seed company will also ensure their heirlooms are ethically sourced by means of paying royalties for those preserved by Native, Amish, or Mennonite communities. 

Final Thoughts On Ethical Seed Companies

Whether you’re digging into eco-friendly landscaping or a self-sufficient homestead, open pollinated sustainable seeds are the literal root of garden sustainability, and thus our planet’s.

The only way out of the dirt and darkness toward the proverbial light is a world where sustainability is our collective focus. 

Roll up your sleeves, strap on your gardening gloves, and experience the real-life alchemy that comes from letting the magic of sustainable seeds unfurl in your own backyard—or just your apartment garden.

Plus, we’ve yet to mention the emotional and mental health benefits that gardening blooms internally for its greenskeepers!

So please, let’s berry the hatchet for once and for all with GMOs and encourage others to join the fight by sharing this article with your Walmart produce loving friends (yikes!).
