David Hosack, Thomas Jefferson, and the Botanical Promise of Lewis & Clark

September 10, 1806
Dearest readers,
On this day, David Hosack—the celebrated American botanist, physician, and founder of Manhattan’s Elgin Botanic Garden—wrote from New York to Thomas Jefferson at Monticello.
His heartfelt letter, composed amid the excitement of scientific discovery and westward exploration, sought not only friendship but seeds—seeds of wonder and scientific promise.
As the Lewis and Clark Expedition carried American curiosity into the Missouri frontier, Hosack implored Jefferson,
“If, sir, the gentlemen who are at present on their travels to Missouri discover any new or useful plants I should be very happy in obtaining a small quantity of the seeds.”
At the time, Hosack’s botanic garden, a jewel of American horticulture, boasted nearly 2,000 species, carefully collected, catalogued, and grown to further both science and the country’s practical ambitions.
Hosack knew well that botany was the lifeblood of progress—medicine, agriculture, the useful and ornamental arts all depended on the green bounty of plants.
He also trusted Jefferson—America’s pre-eminent plant enthusiast—to steward the discoveries returned from the continent’s wildest reaches. With each new species came the hope of future cures, crops, and untold uses.
Though Hosack never received all he wished from the pioneering botanizing of Lewis and Clark, his legacy blooms eternal: in the correspondence that quickened America’s first scientific networks, in the grand ambitions seeded at Elgin, and in every explorer moved to view a humble seed as the beginning of a new story.
