Kentucky Bluegrass, or Poa pratensis, is not actually blue, nor is it originally from Kentucky.

This popular grass owes its name to the bluish-purple buds that appear when it’s allowed to grow to its full height, and to the fertile soils of Kentucky where it thrived when Europeans settled in America.

The Origins of Kentucky Bluegrass

From Europe to American Meadows

Kentucky Bluegrass is native to Europe, Asia, and Northern Africa.

It was introduced to North America by European settlers and traders.

Despite its name, this grass found its way into the American landscape, particularly thriving in the northern regions of Kentucky, which were known for their vast meadows of blue-flowered grass.

The Blue in Kentucky Bluegrass

The “blue” in Kentucky Bluegrass comes from its bloom.

When allowed to grow naturally, Kentucky Bluegrass produces small blue flowers that give fields a bluish tint from a distance.

However, since the grass is commonly kept mowed in lawns and parks, this characteristic blue hue is rarely seen, leaving many to wonder about the name’s origin.
