Professional Grower | Home Gardener



Harris Seeds supports the success of organic growers by offering high quality organic and untreated seeds, organic plugs & liners, and OMRI listed supplies for organic growing. We offer a small number of organically produced flower seed varieties, and the majority of our flower seed varieties for cut flower and bedding plant growers are offered in untreated form.

Many organic and sustainable growers market directly – via Farmers’ Markets, farm stands, or CSA’s – where customers look for exceptional eating quality.
Both gardeners and professional growers using organic methods need varieties that grow with vigor and yield well.
Disease Protection.
Varieties that are bred to naturally withstand disease pressure require fewer inputs, which fits well with organic growing.

These traits – taste, performance, and disease protection – are exactly those found in Harris Seeds’ high-quality hybrid and open pollinated varieties. To make these varieties more available to growers and gardeners using organic methods, we have introduced many of our best varieties in untreated seed.

Organic seed is clean and untreated, and it was grown under Certified Organic conditions. It is allowed for use in Certified Organic production.
