Still growing strong more than two centuries later, D. Landreth & Sons is the oldest seed company in the United States and is celebrated as one of the most influential forces in American horticulture. The company has introduced and chronicled the development of some of the most popular vegetable and flower varieties ever grown, many of which are now heirlooms. In 1798, Landreth brought the first Zinnias into the country from Mexico. In 1808, Lewis and Clark sent seed samples collected on the Journey of Discovery to Landreth for cultivation. In 1811, Landreth introduced the first white potato to America (prior to this introduction, potatoes had been yellow). Bloomsdale spinach, the extra early pea, the very first Japanese shrubs and plants in the country (brought back from Japan by Commodore Perry) – all were also Landreth firsts and the list goes on and on.
Landreth’s place in history includes so much more than what was planted in the ground. The company also created tools and machines to work the soil for optimal sowing and growing. Landreth pioneered the first grain and seed threshers, built some of the first mowers, reapers, plows, and corn shellers, and, in 1872, developed the first steam-powered tractor for plowing fields. In addition, David Landreth himself published the first floral and horticultural magazine in Philadelphia, and also served as the president of the U.S. Agricultural Society for several terms.
