Where To Buy Organic Seeds

< grow >       
Choosing seed awakens the gardener's vision.

There is growing interest among gardeners for untreated, open-pollinated and heritage seeds for vegetable gardening.

The listings below, while not conclusive, offer a range of suppliers of organic seeds in the US and Canada.

When sourcing seed sources through catalogs and websites, look for the following labels which are commonly used to identify the seed characteristics:

Heirloom, Organic Garden Seeds

Raised Garden Beds

Cedar Potting Bench




















  "U" - untreated. These seeds have been produced without the use of synthetic fertilizers, herbicides or pesticides. or subject to genetic modification.
"O" - organic.
These seeds are taken from parent plants which have been organically grown.
"OP" - open-pollinated.
These seeds are capable of reproducing themselves. Open-pollinated seeds can be dried and saved over winter, then used for planting in the next season.
"H" - heritage (or heirloom).
These seeds are saved and passed down through generations by gardeners looking to preserve their genetic diversity and the unique qualities of the plant they produce. Heritage seeds may be carried by some of the smaller seed companies, but are more commonly found through local seed exchanges such as "Seedy Saturdays", the Seed Saver's Exchange and Seeds of Diversity (Canada).
Hybrid seeds have been developed to enhance a plant's growth and fruiting, as well as hardiness. Hybrids are produced by cross-pollinating plants of different varieties in order to improve the characteristics of the resulting offspring. However, hybrid seeds do not always reproduce true to type. That is, second generation plants may produce different results. If you are buying hybrid seeds, look for seeds which are labelled as reproducing "true to type".

Biodynamic seeds are from farms or gardens which use Biodynamic practices of managing land for ecological balance. The organic growing methods and planting cycles are integrated with the local environment where possible.

It should be noted that while organically-grown crops have clear benefits to those grown by industrial agriculture, there is no consensus that organic crops grown from conventional seed are significantly different from those grown from organic seed. Some growers are required to use organic seeds to maintain an 'organic' certification, but home gardeners may find conventional seed, in many cases, comparable to organic in producing good results.

Most farmers and gardeners would agree, however, that preserving genetic variety is key to overall species health. By using good quality seeds, planting local heritage and heirloom varieties, and learning to dry and store seeds, we are contributing to developing and preserving our future food bank.
