Flora Graeca is a publication of the plants of Greece in the late 18th century, resulting from a survey by John Sibthorp and Ferdinand Bauer.

From March 1786 to December 1787 they surveyed the plants and animals of the eastern Mediterranean, Sibthorp collecting and describing, Bauer making dried specimens and producing colour-coded sketches.

Bauer's work, including around a thousand intricate and annotated sketches, is now regarded as one of the finest examples of botanical illustration.

The scarcity of the early first editions led to doubt of their existence, the rare book is at the higher end of trade.

It was during a period of increasing interest in horticulture and highly desired exotic species were described, many would become perennials of the English flower garden.
