VilmorinMikado USA, Inc.


Shamrock Seed Company was established in 1983 with the purpose of providing quality vegetable seeds direct to commercial growers in major production areas. Shamrock has the distinct advantage over most competitors by using a direct marketing with a quality sales force that has been strategically placed in important growing regions.
In 2013, Shamrock Seed Company was acquired by Vilmorin. As part of Vilmorin, we are backed by the latest technology, and our genetics are now supported on a global scale. Our headquarters is in Salinas, “The Salad Bowl” of California. Our focus is and has always been our customers, and finding solutions to fit their needs.
