Where to Buy Heirloom Garden Seeds Online – Trusted Sources

I’m a part of an online gardening group that has exploded with activity since last year’s pandemic began. There are so many new gardeners and with that comes many more people buying local seeds and seedlings.

I know last year, I got a late start on my garden/seeds.  When I went out to buys seeds and seedlings, nearly everything was wiped clean.  I learned my lesson and started ordering seeds late in the summer to be better prepared for this year’s garden.

Today. I’m sharing with you a list of sources to buy your heirloom garden seeds online.

I generally try to save my seeds, but there are definite benefits to buying seeds as well.

But before I get into my sources, you may be wondering what the difference is between heirloom, organic, open-pollinated, and hybrid seeds.


These seeds are known as “old” seeds that are at least 40 years old, and they are passed down from generation to generation through open pollination.  This open pollination has been done naturally and without intentional changes to the plant/fruit’s characteristics.  As a result, the plants have had slight characteristic changes over time.  Many of these changes are super beneficial because they may make the plant more suited to climate changes, new diseases, or pests.  These are hardy seeds and, by far, my favorite.  (See below where I discuss open-pollinated seeds)


Organic seed farmers cultivate seeds with extreme care to ensure no chemical exposure to the plants and subsequent fruit.  It costs a pretty penny for the certification, and the seeds tend to be more expensive.


Plants that are pollinated by insects, birds, wind, etc., produce open-pollinated seeds.  The fruit from this type of seed can produce new seeds that are quite a bit different from the original seed.  The fruit’s seed can change so drastically because the little bee pollinating your blossoms travels from plant to plant and will likely cross-contaminate the pollen and genetic makeup to another plant.  Thus, you end up with a different variety.  Not all open-pollinated seeds are heirlooms.

A word of warning if you are growing open-pollination seeds for seed-saving.  You will NOT notice contamination in the pollination until you plant that fruit’s seed and get the new offspring (this is the 2nd generation of the original seed).

To illustrate this, let me tell you what happened last year.  My friend gave me some spaghetti squash seed to plant.  I thought all was well, but the fruit the seed produced looked like zucchini-colored spaghetti squash.

For this reason, you will want to take more precautions when saving these seeds for next year’s garden since cross-pollination results are unpredictable.


These types of seeds are intentionally cross-bred to produce more desirable fruit.  This doesn’t been they are genetically modified or engineered seed.  It just means the seed has been cross-bred to produce a better product, more uniform shape, disease-resistant, etc.  This is NOT a bad thing in itself.  Hybrids are created in a lab, and the seed produced from these plants should not be saved for future gardens.

For example, check out this article and see what these fruits used to look like many years ago.

Now you know what kind of seeds you’d like to buy, here are some of my favorite sources for buying heirloom seeds online.  Many of these places also sell organic seeds.
