Victor Schaff, recognizing the need for low water use plants, founded S&S Seeds in 1975 with the hope of developing a business by sharing his experience in the collection and use of drought tolerant native plant seeds. This willingness to share experience with others along with a dedication to provide the very best service has enabled S&S Seeds to become a primary wholesale supplier to landscape contractors, government agencies and seed distributors throughout the United States and abroad. At S&S Seeds, we feel our chief distinctions are service and fine quality seeds. We have research and development trial fields for evaluation of new and old species. Our production fields and continued extensive collections of native plant seed allows us to offer seeds for more than 900 plant species, including wildflowers, native and reclama- tion grasses, trees, shrubs, and native plants. Our large and diverse inventory enables us to ship product the same day it is ordered. By utilizing our state of the art seed conditioning equipment to process seed and by continually testing for purity, germination and pure live seed counts at certified laboratories, top quality seeds are assured. Our professional staff is available to work with you to design seed mixes for each particular project site. Careful consideration is given to site condition, soil type, climate, available moisture, and the desired visual effect. Germination, purity and seed count are also considered when recommending planting rates to guarantee a properly balanced seed mix. We also specialize in custom seed collections for projects which require site specific species. If increases of seeds or plants are necessary to complete the project, S&S Seeds has production facilities available. Consistent with our desire to be of service to you and provide information of value we have designed this brochure to be helpful and informative.
