On May 28, 1767 Jefferson observed "Snap-dragon" blooming at Shadwell, his childhood home.1 and four years later, he listed this native of southern Europe among the hardy flowers to be naturalized in a "shrubbery" at Monticello.2 Jefferson's reference is the earliest known mention of this plant in an American source .3

This southern European native has been cultivated in American gardens since the mid-18th century. Philadelphia nurseryman Bernard McMahon included the "Common Snapdragon" in his 1806 American Gardener's Calendar as a biennial flower.4 By the mid-1800s, many snapdragon cultivators had developed a variety of colors and forms. In 1890, however, Peter Henderson noted in his Henderson's Handbook of Plants and General Horticulture that "this plant, in its wild state, is very commonly found growing on the tops of old walls."5 It became a favorite for Victorian bedding schemes.6

The Snapdragon is an excellent example of a flower whose appearance has changed little in three hundred years, and Jefferson's Snapdragon might have been the purple-flowering species that now grows wild throughout southern Europe. The snapdragon is a summer-blooming flower grown as an annual with deep wine-red blossoms on upright stems.
