Herbal Seed Suppliers and Nurseries: Ethical Sources for Medicinal Seeds & Plants.

The freshest medicine on the planet comes right from our own backyards and gardens. When we grow a personal apothecary of herbs, we have an immense and intimate relationship with their quality and integrity. For this reason, starting with healthy seeds and organically-nurtured living plants is paramount!

You might be wondering: what constitutes a healthy seed source for medicinals? Here are some key terms used to describe different types of seeds and plants, and how they relate to herbs in particular.

Freshly cleaned passionflower seeds (Passiflora incarnata).

Heirloom seeds come from old-time stock; their ancestors are typically pre-WWII varieties that have been handed down for generations. Heirlooms are typically regional varieties, with specific traits that have been hand-selected over the years. Heirloom seeds are open-pollinated and their characteristics typically remain stable (true to seed) from season to season. Heirloom varieties are more common in the vegetable realm as compared to medicinal and culinary plants. Many herbs have a long history of cultivation, with seeds being handed down over generations. Still, there are few named regional varieties—or recognized heirloom varieties—of herbs.


Open-pollinated seeds are pollinated by insects, wind, birds, and other natural forces without human intervention. These seeds are generally easy to save and come up true to type. Almost all herbal seeds being sold are open-pollinated.


Hybrid seeds are the result of cross-pollinating two species or two varieties (within a species) to produce a desired combination of characteristics. Hybridization happens naturally in many plant groups (genera), humans have been breeding plants for desired traits for millennia. Don’t confuse hybrid seeds for GMO seeds! They are in no way the same.

There are some wonderful hybrids out there; just keep in mind they are not true to seed from year to year, compared to open-pollinated seeds. If you save seed from a hybrid plant, there’s no telling what the traits of its offspring will be, but it’s likely that they won’t have the traits of its parent plant. You generally won’t find herbal seeds that are hybridized but sometimes potted herbs are hybrids.


Cultivars, short for cultivated varieties, are the result of hybridization, selection, or natural mutation. Cultivars typically need to be propagated asexually (through division or cuttings) to remain true to type. This is why it’s better to purchase starts (little potted plants that have been divided) of mint varieties like peppermint or chocolate mint than grow them from seed—the offspring typically won’t have the same desired characteristics as the parent plant. You’ll end up with a mint mutt if you plant it from seed!


GMO (genetically modified) seeds have had their genes modified in a laboratory setting to produce desired qualities through practices like gene-splicing. It’s still unclear what the long-term ramifications of GMOs will be, but concerns include loss of genetic biodiversity (GMO’s can cross-pollinate with other plants) and impacts on ecology and animal health, including humans, insects, and so on.

You probably don’t need me to digress on the importance of cultivating seed sovereignty or the dangers of mega-corporations taking control of our seeds—patenting them, modifying them, and controlling their distribution.

But I will say this: channeling our money to ethical, organic, and sustainable seed savers is an important choice in this era of big agribusiness.

The seed companies and herbal nurseries that made our lists (we’ve got one for you too, Canada!) primarily use organic methods or source from organic farms (even if they’re not “certified organic”). That said, you’ll need to vet each source yourself; some seed sellers offer both conventionally grown and organic seeds. Some are well-established businesses with plenty of herbal street cred, while others are smaller, newer additions to local growing scenes across the country.

Many of these companies ship internationally, but if you prefer to keep things local, we encourage you to seek out suppliers in your area (you’ll notice we’ve also created a separate list for small-scale and regional suppliers in the United States). And on that note, keep in mind this is not a comprehensive list.


Did we miss an all-star seed supplier? It’s likely the omission was not intentional! Let us know in the Comments section at the end of this article.

P.S. If you’ve got questions about herb gardening, we have a growing library of posts on our blog devoted to cultivating medicinal herbs. Here are some of the crowd favorites:
