03 "I have been dealing with Harris Seeds for several years and they are my go to seed source. As a small farmer experimenting with various crops and varieties, I appreciate the various seed amounts offered for purchase. The website is informative and easy to use, especially for a "non-tech person". Everything arrived when scheduled and in perfect condition. I also like supporting a company that has been around for so long.

- Bonnie L.

Our History

Generations Of Growers Have Trusted Harris Seeds

Since 1879, farmers, homesteaders, and backyard gardeners like you have trusted Harris Seeds for quality vegetable seeds, flower seeds, plants, and supplies.

Founded in Rochester, N.Y.  by Joseph Harris, an English immigrant, the company remained in the family for three generations, becoming a leading seed supplier thanks to its wide selection of superior strains of vegetables and grains. 

Now under private ownership, Harris Seeds continues in the footsteps of the founding family, committed to the same mission Joseph had 145 years ago: to provide you with the finest quality seeds and products at fair prices.
