Harvested from the gardens at Monticello.
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 appreciation of the natural world around him. Philadelphia nurseryman Bernard McMahon sold Prickly Poppy, "Mexican Argemone," in 1804, which produces pale yellow flowers and attractive green and white-variegated leaves tipped with prickly spines, and reseeds readily. Jefferson-documented: This plant was documented by Thomas Jefferson in his Garden Book, Notes on the State of Virginia, or other writings.
