Do you ship Internationally?


We do ship seeds internationally. We also offer a phytosanitary certificate which may be required by your country's customs laws. you can find and pay for your phytosanitary certicate at this link:

Canadian Customers prior to January 2012 were able to have shipments arrive without many issues. As a result of changing laws though, many shipments have been stopped or rejected at the border. As we understand it, there is no need for a phytosanitary certificate if "the net quantity of the seed for each lot (all packages of a lot added together) exceeds a small lot (500 grams or less for small seeded crop types or 54kg or less for large seeded crop types)" For more information you can refer to Canadian Guidance Document Repository (GDR) published by the Canadian Food Inspection Agency (CFIA)

How many tobacco seeds are in a seed packet?


There are approximately 100 or more tobacco seeds in each standard seed packet, though we do offer bulk tobacco in larger sizes.


Are your seeds chemically treated?


We do not chemically treat our seeds and since we don't buy from out of country, the USDA does not treat our seed like many seed companies. Don't assume that if a company uses the word "heirloom" that it is grown here in the US. In fact, we get hundreds of emails from companies in China and India trying to sell us cheap chemically treated "heirloom" seed.

How long will my seeds last?


The shelf life of the seeds varies based on the individual seeds. Onions and Carrots have the shortest shelf life at 2 years under usual storage conditions. If stored in a refrigerator the shelf life could be extended possibly to 4-5 years. The other seeds vary from 3-7 years under normal conditions, allowing for much longer if kept in a refrigerator. Freezing is problematic as the seeds, if not properly dried, can be killed through the freezing process - refrigeration is a better bet.

Seeds do need cool places for extended storage, but if you have any doubt that the seeds have any moisture, please do not freeze them - either keep them in a cool basement or garage or in your refrigerator as the freezing could possibly kill them. Adding silica gel to the container they're in will help to remove any harmful moisture from the seeds, prolonging their lives further. (Silica gel packets can be purchased on our website: Silica Gel Desiccants)

Can I buy seeds to eat or make into food?


We are licensed to sell seed, not food for human consumption. We do not sell anything for human consumption. The seeds are only sold for planting.

Do you sell bulk or wholesale items?


Yes, we do sell wholesale and bulk heirloom seed. We carry heirloom flower, herb and vegetable seeds in bulk pricing. Bulk prices are found on product pages or visit our Bulk Seed page for more information.

Are you affiliated with Monsanto(Seminis) or Syngenta? Are you a dealer/reseller for these companies?


We are not. WE ARE IN NO WAY AFFILIATED WITH ANY GMO COMPANY! Companies that are affiliated or distribute products from Monsanto or Syngenta are listed on their respective websites.

» Syngenta (Select: Commercial Fresh Market: Western U.S. & Canada)

» Monsanto/Seminis (Where to Buy)

We are a family-owned business founded in 2009. We 100% oppose GE/GM crops and their environmental contamination to other valuable food crops. Sustainable Seed was founded with the mission and purpose to protect non-GM seed.

Are you Certified Organic?


Yes, we are certified organic seed handlers and the farm itself is USDA Certified Organic. However, we do sell both conventional grown seed and organic seed to meet the needs of all of our customers.

How are you different from other organic heirloom seed companies?


We are proud to be one of the VERY few Organic + Heirloom seed companies out there, meaning most of the seed companies out there sell heirloom vegetable seeds, but very few sell Certified Organic Heirloom Seeds. Click here: to read more about the difference. However, to further answer the question, one of the most important distinctions about Sustainable Seed Company is that we actually sustainably farm and grow many of our own organic heirloom seeds right here on our Certified Organic farm. Very few seed companies do this -- in fact, none to our knowledge use green technology like our wind turbine and solar panels that we use to sustain our farm's energy needs. We are a company with one foot in the past and our eye on the future. We remember the lessons our grandparents taught us and embrace the green technology of tomorrow for those that follow in our footsteps. We want to leave the world a cleaner and greener place than how we found it. Yes, you CAN produce food and seed without the use of Genetically Engineered crops, toxic pesticides and destructive herbicides. We are changing the world one seed at a time!

What is the best way to contact you?


Our Customer Service department can be reached at Since we are an internet-based company, we check our email constantly during the day. This also allows us to track the question and resolve any issues on the whole quickly. 90% of the time you will get a much faster email response than you will get a phone response and we return messages within 2 business days.

Don't you think you are losing a great deal of business by not printing a paper catalog?


This is the most controversial decision we have made as a company. We knew taking a stance against paper catalogs was not going to to be easy, as people have been doing it this way for over 175 years. However, someone has to make a step to do something"first". Our environmental reasons are detailed on our page as to why we do not print a catalog. Providing an online catalog allows us to update quantities on rare seeds immediately and cuts costs. No work hours are spent calling customers, offering substitutions, or refund checks. Nor do we have to open envelopes, interpret handwriting on orders, and hand-process them into the system. This saves us expense and resources. We feel strongly that we would rather pass these savings on to our customers, so that we can keep offering our seed packets at our low rates.
