Sutton & Sons, Ltd. seed company was founded by John Sutton under the name House of Sutton in 1806 in Reading, Birkshire, England. When John's son, Martin Hope joined him as a partner in 1836, the name changed to Sutton and Son. The company is an international supplier of seeds, bulbs, plants, bushes and other horticultural products. In 1858, Queen Victoria bestowed Royal patronage upon the company giving them the honor of providing seeds to the Royal households. This honor continues with the reign of Queen Elizabeth II. Beatrix Farrand ordered seeds for use in the Dumbarton Oaks Gardens.
