The flag of the Dutch province of Friesland consists of seven blue and white diagonal stripes with seven red seeblatts, which are stylized lily leaves. Due to the fact the seeblatts are red, many mistake them for hearts, but the instructions for the flag specifically say they should not be heart shaped. The seeblatts represent ancient regions of the province, and the blue stripes represent rivers in Friesland. This flag was adopted on July 9th, 1957.
