The Margraviate of Brandenburg and the Ducal of Prussia became the Kingdom of Prussia in 1701. Friedrich III, the Elector of Brandenburg, was crowned as Friedrich I. Berlin, a small trading town, merged with four neighboring towns: Friedrichswerder, Cölln, Friedrichstadt, and Dorotheenstadt, to become the capital.

Iris germanica - The German iris, also referred to as the bearded iris, is a rhizomatous perennial. Rhizomatous plants describe flowering plants with a modified subterranean stem system. This feature is also called a rootstalk and is used by the plant to store nutrients. The rootstalk will generate new plants if separated. The German iris is a cultivated hybrid originating from Europe; it is not a wild species of plant. There are approximately 300 species of iris plants in the family Iridaceae, Greek for “rainbow.”
