This week we’re enjoying irises in Central Park. Jacob Bigelow (1786-1879) included the native iris, Iris versicolor or Blue Flag, in his “American Medical Botany,” 1817-1820. Bigelow noted its use as a cathartic and diuretic. “American Medical Botany” was an early American botanical as well as an early instance of color printing in America. The plates were actually printed in color, rather than being colored by hand afterwards.
