Jefferson-documented

This strong-growing, medium-sized shrub has long been in cultivation, since at least the sixteenth century, and is the most commonly known species. Its origins are obscure but it is believed to be native to Northern Italy, Austria, and Central Romania. Thomas Jefferson's Garden Book entry on April 19, 1807 notes: "planted 9 Philadelphus coronarius, Mock orange in the 4 circular beds of shrubs at the 4 corners of the house".
