Why Kentucky Is Called the Bluegrass State?

Kentucky was admitted into the Union as the 15th state on June 1, 1792, splitting from Virginia in the process. It is known as the "Bluegrass State", a nickname based on Kentucky bluegrass, a species of grass found in many of its pastures, which has supported the thoroughbred horse industry in the center of the state.

Why is Kentucky called bluegrass?

The name Kentucky bluegrass derives from its flower heads, which are blue when the plant is allowed to grow to its natural height of 60 to 90 cm (2 to 3 feet). Poa pratensis is the type species of the grass family Poaceae.

Why is Kentucky bluegrass not blue?

Kentucky Bluegrass is not named for its leaves because they're always green. Since it's used mainly for lawns and kept short, it always appears green.
