On June 18, 1767 Thomas Jefferson recorded in his Garden Book that "Argemone put out one flower" in his garden at Shadwell. On July 18 he noted another Prickly Poppy flower and observed that it was "the 4th this year," a testament to Jefferson's almost childlike appreciation of the natural world around him. Philadelphia nurseryman Bernard McMahon sold Prickly Poppy, "Mexican Argemone," in 1804.
Jefferson listed "tansey" among the "Objects for the garden this year" in 1794. It is not known exactly how it was utilized at Monticello, but its bitter, aromatic leaves were frequently used for flavoring, especially in puddings and omelets. Tansy is a native of Europe but is now common across North America.
This unusual European mallow-like perennial with purplish-pink flowers was planted in an oval bed at Monticello on April 18, 1807. Later that year, however, Jefferson's granddaughter wrote to him that it and the "pinks Carnations Sweet Williams Yellow horned Poppy Ixia Jeffersonia everlasting Pea . . . Columbian Lilly Lobelia Lychnis double blossomed Poppy & Physalis failed, indeed none of the seeds which you got from Mr. McMahon came up."
