Types of Seed
Before we discuss where to buy seeds, it's important to know the different types of seeds.
Today's topic on what hybrid, heirloom, and genetically modified seeds mean is where I see a lot of confusion and misinformation that is just wrong. I wanted to address this for those that are new to gardening or are just learning about the differences so you can learn about these terms and their proper meaning. There are three types of seeds.
- Heirloom Seeds
- Hybrid Seeds
- GMO Seeds
Heirloom Seeds
Heirloom seeds are open-pollinated seeds from varieties that have been handed down for generations (most sources say they're heirloom if you can trace them back at least 50 years).
If I'm being honest, heirloom seeds are my favorite out of the three seed types. When they are planted they produce the same plant with the same characteristics of the parent plant that you saved the seeds from. This assumes you did your seed saving correctly when it comes to plants that cross-pollinate or are self-pollinated.
Plants that cross-pollinate, squash for example, need special care to be sure they don't cross-pollinate. Using methods such as hand-pollinating or seed netting to keep them pure will ensure you don't get crosses that are different from the parent plant.
Hybrid Seeds
In the context of hybrid seeds, we're talking about hybrid seeds that you purchase in the store. So F1, the first generation hybrid. These seeds are created by companies or scientists in a lab, not a natural cross-pollination that happens with heirloom varieties.
It was about the 1940s when large seed companies started creating their own strains of hybrid seeds. For example, two varieties of a tomato plant that they have put together in a lab to create a different tomato plant. But it's done in a lab and not a natural cross-pollination as we get with heirloom plants.
These hybrid seeds are created by combining two varieties of the same plant where the best characteristics from each variety are chosen to create a new hybrid plant. One may be more disease resistant and one offers a higher yield, etc.
There's nothing wrong with hybrid seeds, you're just not able to seed save from them and have fewer varieties to choose from.
GMO Seeds
The next type of seed, and this is where a lot of confusion comes in, are GMO seeds. A lot of people think genetically modified seeds and hybrid seeds are the same thing and have been occurring for hundreds of years. This is just not true.
Let's dive into GMOs a little bit. Genetically modified organisms, or seeds, in this case, are not for sale at your local big-box store or from regular seed companies. That's not to say that the seed that you purchase might not have genetically modified stuff in them, but they are not purposely genetically modified.
Farmers, usually big agriculture, purchase GMO seeds and you have to have certificates that you have purchased their seed. We'll talk a little bit more though about how there's contamination with some of the crops and seeds you are getting at the store because of GMOs.
Genetically modified seeds are seeds that are created in a lab by splicing or combining different organisms, which can be viruses, bacteria, and even animal DNA, to create a patented plant.
For example, Monsanto created GMO corn that has genetic material from bacteria, Bacillus thuringiensis, that produce an endotoxin.[1] They also have GMO corn that is Roundup® resistant which means the crops can be sprayed with the herbicide Roundup® and the plant won't die due to gene altering. Sadly, over 90% of domestic corn in the U.S. is genetically modified.[2]
The most popular GMO crops are alfalfa, canola, corn, cotton, papaya, soybeans, summer squash, and sugar beets. Recently the USA approved a GMO apple as well.
While you aren't going to find GMO seeds on store shelves, you may find foods that have ingredients that are GMO, such as soybean or canola oil.
If it's labeled non-GMO, which is what I look for personally, then it's been tested and sourced from a non-genetically modified crop. Anything that falls in the certified organic isn't tested as often or as stringently as the non-GMO label but when they do test for it, if it does show GMO, then you can't have the organic certification.

Why I Only Choose Heirloom Seeds
When you go to the store to purchase seeds or order seeds online you only have heirloom or hybrid seeds available to you.
Now, there is nothing wrong with hybrid seeds. If you have no interest in heirloom varieties, or seed saving and want to grow hybrid seeds, that's just fine. I don't want people to feel ashamed because they're using hybrid seed.
Personally, we like to save our seeds and store them for the next year or share with family and friends. I don't always save seed every year, but I do a complete heirloom garden because I want to make sure that I'm supporting heirloom seeds (and companies that sell them) because there are varieties that have almost been completely wiped out and lost in a short period of time; less than a hundred years since we've had hybrid seeds available to us.
I also believe that heirloom varieties have better flavor and there are a whole lot more varieties. I get super excited about all the stories and the different varieties, colors and unique things you'll never see on the grocery store shelf. You just won't see the many different options with a hybrid that you do with all the different heirloom varieties.
I'm very biased towards heirloom if you can't get tell, but I'm being upfront and center about it.
How GMO Effects Pollination
The reason I bring this up is because of the way that crops pollinate. Especially when you have big agriculture, which is planting these GMO crops in huge fields. Corn, especially in the right conditions, can cross-pollinate up to two miles. Now that means that the conditions are just right…the land is flat, the wind is just right.
There's more that comes into play but it can be up to two miles that it can cross-pollinate. So when there are large fields of GMO corn it's going to cross-pollinate with whatever corn is around. It doesn't discern which field is GMO and which one isn't.
This happens with the other crops like summer squash as well, since they cross-pollinate with all kinds of different summer squash varieties.
So, as the years have gone by, we've had more genetically modified crops in our large agriculture making its way into our backyard gardens and seeds. You're going to find cross-contamination within some of those crops, even though the original seeds/plants were not GMO when purchased or seed saved.
What is the Safe Seed Pledge?
The safe seed pledge is a voluntary pledge made by seed companies to not buy, produce or sell GMO seeds. If a seed company has signed the Safe Seed Pledge, it's a good bet they're a safe company to buy from.
The Safe Seed Pledge reads:
Agriculture and seeds provide the basis upon which our lives depend. We must protect this foundation as a safe and genetically stable source for future generations. For the benefit of all farmers, gardeners and consumers who want an alternative, we pledge that we do not knowingly buy or sell genetically engineered seeds or plants. The mechanical transfer of genetic material outside of natural reproductive methods and between genera, families or kingdoms, poses great biological risks as well as economic, political and cultural threats. We feel that genetically engineered varieties have been insufficiently tested prior to public release. More research and testing is necessary to futher assess the potential risks of genetically engineered seeds.

Where To Buy Heirloom Seeds
Obviously, I'm an heirloom seed girl, but where do we get our heirloom seeds? These are the BEST places to buy heirloom seeds, in my humble opinion.
Baker Creek
If you're not familiar with Baker Creek Heirloom Seeds (or “rare seeds”), they're like the showcase of heirloom seeds as they have one of the largest selections with over 1,800 different varieties of vegetables, flowers, and herbs (woah!).
At the time of this updated post, they had actually taken their website offline due to backorders they are trying to fulfill. Do take note that many seed companies are extremely overloaded and on short supply due to the pandemic!
Baker Creek has done a great job of collecting amazing varieties from all over the world and educating people on the history of each seed. In fact, they're selling many Asian and European seed varieties that date back to the 19th century, plus heirloom seeds from over 75 other countries!
They are family-owned and have a beautiful farm that you can actually visit, see them in production, and buy seeds, all in one trip. They also have a really great heirloom seeds catalog done in a magazine type style.
You can order online at their easy-to-use website, but I love perusing their catalog to find new crops that I just have to try. They sucker me in! Why yes, I do want that beautiful purple atomic tomato plant this year. And I love the stories that they include on where the different varieties are from, the history, or where they were rediscovered.
Seeds Savers Exchange
Seed Savers Exchange is a great resource to order from online. They have a seed vault where they keep seeds so that we don't lose some of these precious and really rare varieties. Not only do they sell seeds but they do a really good job on education on seed saving and heirloom seeds.
They're a non-profit organization and they focus on preserving seed varieties that came with families when they immigrated to North America (as well as some traditional varieties grown by the Amish, Mennonites, and American Indians).
Seeds for Generations
Another option is Seeds for Generations which is a family business offering heirloom seeds. I have gotten to know Jason and his family pretty well. Jason, his wife, and his kids run the business together. And how sweet is this? He pays his kids for their help with packing the orders. So your order is packed by the kids, who get paid per envelope.
This family endeavor is teaching the kids entrepreneurial and business skills. I really like to support small family-run operations and Seeds for Generations is a great company to support in that regard. I've gotten quite a few herb seeds from them. They also offer some good resources for planning on their website as well.
Those are the main ones that I've personally ordered from and have experience with. There are a lot of amazing heirloom seed companies out there that are passionate about and love heirloom seeds. These companies don't want to see these seeds disappear and are helping to preserve that part of history while providing the seeds and educating people.
Siskiyou Seeds
I'm in love with this company. They offer all non-GMO, open-pollinated (heirloom), family grown seeds from Oregon. They have a fabulous medicinal flowering herbs section like none other I've ever seen. I ordered a lot from them this year.
For those in a cooler northern climate, they have some varieties of heirloom vegetables I haven't found in other places that will grow well in our shorter and cool climates.
Johnny's Seeds
Johnny's seeds is an original signer of the Safe Seed Pledge for all non-GMO seeds, they do carry some hybrids as well as organic heirloom seeds.
Johnny's is an employee-owned seed company which sells more than 1,200 varieties of hybrid, open-pollinated and heirloom seeds (including vegetables, flowers, and medicinal and culinary herbs).
If you're looking for more than seeds, Johnny's would be a great place for a “one-stop shop” because they also offer many great soil amendments, organic pest controls (although I prefer to keep pests out of the garden a more natural way), and even gardening tools, equipment and accessories.
Botanical Interests
Botanical interests is a signed member of the Safe Seed pledge for all non-GMO seeds, they also carry 238 organic, 349 heirloom, and 29 native varieties of vegetables and flowers.
