Flower Moon origin
The Old Farmer's Almanac, which first began publishing the names for the full moons in the 1930s, recorded the name given by American tribes to the full moon in May as the "Flower Moon" because of the flowers blooming across North America, signaling abundance and the coming of Spring after a cold, hard winter.
Synopsis
The book investigates a series of murders of wealthy Osage people that took place in Osage County, Oklahoma, in the early 1920s—after big oil deposits were discovered beneath their land. After the Osage are awarded headrights in court to the profits made from oil deposits found on their land, the Osage people prepare to receive the wealth to which they are legally entitled from sales of their oil deposits.
