North America runs from short Canadian summers to the long, hot seasons of California and the Southwest, so no single strain suits everywhere. Here are our 20 top outdoor picks for the continent, grouped by climate and chosen only from three ranges we know best: Satdica Bulk Seeds, Europa Seeds and Freedom of Seeds.
Please note: this is a guide for seed collectors, not growing advice. Freedom of Seeds sells seeds as souvenirs and collectibles for adults. Laws differ widely across North America and importing seeds can be illegal, so please read the section on the law below.
How we chose these 20 strains
Every strain here is in stock at the time of writing and was picked using the details on its own listing: its listed outdoor finish, notes on hardiness such as mould or cold resistance, links to North American genetics and, for three picks, triploid genetics from Satdica Bulk Seeds.

Cannabis seeds and the law in North America
Canada: viable cannabis seeds are treated as cannabis under the Cannabis Act. The Canada Border Services Agency states that importing cannabis without a permit or exemption issued by Health Canada is illegal.
United States: cannabis remains federally controlled, and state laws differ. A federal change to the legal definition of hemp is scheduled to take effect in December 2026 and is reported to exclude viable seeds from plants above the 0.3% total THC limit. Check the current federal and state rules, including those on importing seeds.
Mexico and elsewhere: please check your national and local rules.
This is a general summary, not legal advice, and the law can change.
