First edition of the first notable horticultural work and nursery seed catalogue printed in the United States by this Irish-American nurseryman, who corresponded and traded specimens with President Thomas Jefferson at Monticello, as well as cultivated specimens collected during the Lewis & Clark expedition. McMahon (before 1765-1816) immigrated from Ireland during political unrest, and by 1802 had established his popular nurseries including greenhouses, experimental gardens, and hot houses near the Germantown Turnpike between Philadelphia and Nicetown. These contained useful and ornamental plants adapted to the American climate, and in this detailed volume he outlines month-by-month the instructions for erecting and laying out the plants, their cultivation, and has incorporated as appendix detailed catalogues of 18 separate classes for available specimens. Eventually McMahon was able to cultivate and began selling a variety of plants collected from the Lewis & Clark Expedition, including a fragrant currant (Ribes odaritissimum), and he also successfully cultivated Osage orange trees (Maclura pomifera) which were among the most celebrated specimens. The book became a classic work in the United States, reprinted in 11 editions from 1806 to 1857, and urged American gardeners to incorporate indigenous species into their ornamental plantings.
