Types of Seeds

• Non-GMO – Just say no to GMO! Every company on this list of places to buy vegetables seeds has signed the Safe Seed Pledge, meaning they pledge to not buy, sell, or trade genetically modified seeds.
  
• Organic – Organic seeds are harvested from plants that were grown and processed using certified organic farming practices (e.g. no chemical pesticides). As much as possible, we try to buy certified organic seeds; they’re better for the environment, pollinators, and farmworkers alike! Not every company on this list is completely organic, but most offer organic options.
  
• Heirloom – An heirloom refers to a variety of vegetable or plant that is at least 50 years old and is either open-pollinated or self-pollinated (not hybrid), according to the Seed Savers Exchange. An heirloom variety usually has a story or special significance, such as a history within a particular community, culture, farm, or family.
  
• Hybrid – Hybrid seeds (usually denoted with an “F1” or “F2”) are created when two different varieties are bred or cross-pollinated, either by nature or people. The goal is typically to enhance beneficial attributes like natural disease resistance or a higher yield. Since their offspring won’t “breed true” to the parent plant, hybrid seeds aren’t ideal for seed-saving, but they are NOT genetically modified.

The Best Places to Buy Garden Seeds

1) High Mowing Organic Seeds

We discovered High Mowing Seeds a few years ago, and they quickly became our top favorite place to buy organic vegetable seeds. They offer a diverse selection with hundreds of wonderful vegetable, herb and flower varieties that are 100% certified organic and non-GMO. Bred to perform well when grown in organic conditions, their garden seeds are strong, resilient, and will respond well to a natural approach in the garden.

High Mowing is an all-around fantastic small company. Based out of Vermont, they pride themselves on sustainable practices and high quality in all aspects of their operations. We were honored to partner with them to create our very own flower seed collection: the Homestead and Chill Prized Pollinator Collection!

2) Botanical Interests

Botanical Interests has a really great selection with many of your favorite standards, some unique varieties, and a decent array of certified organic vegetable seeds as well. Botanical Interests seed packages are beautiful, with pretty painting-style images of the plants. Their prices are also very attractive!

You can often find Botanical Interest seeds in local garden centers and nurseries – making impulse buys or a quick pick-up of “oops, I forgot that!” very convenient. This is a huge benefit for those who like to shop in person instead of online.

My good friend Kevin from Epic Gardening purchased the reputable seed company in 2023 when the owners were ready to retire, keeping all of the staff and integrity in the transition. Use code “deannacat3” to save 5% off gardening supplies, raised beds, OR Botanical Interest seeds at Epic Gardening.

3) Johnny’s Selected Seeds

Johnny’s is a larger seed company based in Maine, but they’re 100% employee owned and overall pretty awesome. At Johnny’s, you will find a huge and diverse selection of garden seeds, including many certified organic vegetable seeds at a fair price. Their site is also very clean and easy to navigate. I especially like being able to filter by attributes like particular disease resistance, maturation dates, organic-only and more. It makes browsing for varieties that would work well in our garden a breeze.

4) Seeds Now

Seeds Now is a family-owned and operated business based out of Southern California. The overall selection of different varieties of veggies, herbs, and flowers is quite good. This is a great place to get organic potato and garlic seed too – they offer a nice selection of both! Their packaging isn’t as “Instagram worthy” as some other seed companies out there, but hey, whatever.

In regards to price, Seeds Now prices are very competitive! They’re on the lower end for most seeds I have seen out there. A bonus is that for each garden seed type, they often offer an even more affordable “sampler pack” size of seeds – great for someone with a more petite garden or who wants to try just a small amount of something.

5) Adaptive Seeds

Adaptive Seeds is a small company based out of the Pacific Northwest, near Sweet Home, Oregon. All of their seed crops are grown on their personal certified organic farms! With a slogan of “Bringing Biodiversity Back”, their seed is 100% organic, and not treated or sprayed in any way.

While they do offer a great selection of seeds that could be grown well in any climate, they also bring to the table some excellent varieties for gardeners specifically in the Pacific Northwest or similar climates. Adaptive Seeds specializes in early-maturing, northern-adapted, winter garden, and cooler weather crops. Even though we’re in California, our temperate coastal climate is perfectly suited for many of their offerings.

Since they’re a very small operation, they do seem a little slower to ship than some other seed companies. Their prices are competitive with other organic sellers. Like Johnny’s and Seeds Now, Adaptive has basic, plain packaging.

6) Seed Savers Exchange

Seed Savers Exchange is a non-profit organization based near Decorah, Iowa. Their mission is: “We conserve and promote America’s culturally diverse but endangered garden and food crop heritage for future generations by collecting, growing, and sharing heirloom seeds and plants.” After hearing nothing but good things about Seed Savers from many of their happy customers, I knew they needed to be included on this list.

In addition to a standard seed “shop” page, there is an entirely separate “exchange” page that you can join – and exchange saved seeds with other home gardener’s across the U.S. I saw SO many varieties I have never heard of there! Very, very cool. The prices through Seed Savers are very reasonable as well.

7) San Diego Seed Company

I first connected with San Diego Seed Company over on Instagram and we’ve become fast friends since. This small, sustainable, woman-owned business is definitely one to support – especially if you live in Southern California or a similar climate! Their focus is offering organic and heirloom varieties that are regionally-adapted for SoCal climates, including veggies, fruit, flowers and herbs. Check them out!

8) Peaceful Valley Farm Supply

With a site domain of www.groworganic.com, you can see where Peaceful Valley’s agenda is. Based out of Nevada City, California, this company is all about supporting the movement for organic, sustainable, small-scale agriculture.

In addition to tons of heirloom and certified organic vegetable, herb, and flower seeds, Peaceful Valley specializes in bare root fruit and nut trees, fruit vines, and even has mushroom cultivation kits. They also have a large selection of potatoes. I think the very first seed potatoes we ever ordered were from here, many years ago! Everything comes in pretty seed packages, with fair prices.

9) Territorial Seed Company

Territorial Seed Company is based out of Cottage Grove, Oregon, owned by a husband and wife team who strive to live a simple and self-sufficient life. The website boasts a large selection of veggies, fruit, herbs, and flowers, including both seeds and living plants like bareroot fruit trees.

They carry both organic and conventional options, often times in the same listing – so use a keen eye when you are placing items in your cart! To avoid any confusion, there is an “organics only” section on their site if that is important to you. Like some other companies, Territorial offers many sizes of garden seed packages by weight, allowing you to adjust for your needs. In looking at their prices, I feel they’re very reasonable and in line with others!

10) Renee’s Garden Seeds

Renee is very proud of her seed company, and the pledge to offer unique, high quality, non-gmo, heirloom and organic vegetable seed varieties. Renee’s Garden Seeds are said to be tested and successfully grown in all major U.S. growing zones. Selections are made with home gardeners in mind. Her tagline is “The Garden to Table Seed Company”. While there may not be quite as many different varieties available as some sites, this company has your basics covered, and then some!  

The packages of garden seeds are very pretty, with artistic watercolor images of the crops. Seed packages are offered in just one size, but at very reasonable prices. Our local Ace Hardware garden center carries Renee’s, so we often pick up miscellaneous packs of things there as needed, and have always been satisfied with the results.

11) Kitizawa Seed Co.

Based out of the California Bay Area, Kitizawa is America’s oldest Asian seed company. The business started in 1917! Offering a selection of over 500 traditional Japanese heirloom varieties, this is the place to go if you love Asian veggies as much as we do. Napa cabbage, eggplant, daikon radishes, edamame, bok choy, and komatsuna mustard greens anyone?

Nothing here is certified organic, but like everyone else on this list, Kitizawa has signed the safe seed pledge against GMOs. Fans of Kitizawa rave about their high successful germination rates.

2024 update: Kitizawa seeds are now available exclusively through True Leaf Market.

12) MIgardener

As the name suggests, MIgardener hails from Michigan, though this small seed company offers a diverse selection of heirloom vegetable varieties that will grow well in any climate. The owner Luke started MIgardener in 2011, quickly growing through his social media presence and infectiously positive attitude.

“We believe gardening should be made fun and accessible to anyone of any skill level,” says Migardener – and that accessibility extends to their generously affordable seed prices. You can browse their site by type of vegetable, or narrow it down by characteristics like “cold hardy”, “container friendly”, “for pollinators” or “partial sun”. 

13) PineTree Garden Seeds

Last but not least, let’s talk about PineTree Seeds. This small family-owned operation is located in New Gloucester, Maine. Their site includes selections of over 1300 varieties of seeds, including many heirlooms and organics. In addition to vegetable seeds, they offer an impressive array of flower and herb seeds, plus an assortment of tools, gardening gear, books, live plants, soap making and crafting supplies. Between the excellent selection and very reasonable prices, PineTree is easy to love.

Due to questionable company ethics, Baker Creek was intentionally not included on this list.

And that concludes our list of places to buy garden seeds.

I hope this article helped you discover some new awesome companies to buy garden seeds from! This list obviously isn’t comprehensive to every single organic vegetable seed seller out there, but I tried to include the most highly-recommended and ones we personally love to support.
