While these two sound similar, they couldn't be more different.  They are both types of bluegrass. One is *desirable* and one is *not*. 

## Kentucky Blue Grass yields a beautiful, lush, dark green lawn while Poa Annua (annual blue grass) spreads rapidly and dies quickly, often leaving you with a patchy lawn. 

Fun fact: Many *homeowners* find Poa Annua undesirable but some *golf courses* find it very desirable.  It grows low and is easier to maintain in this environment.

## Kentucky Bluegrass

- ###  Produces a seed head
- ###  Perennial
- ###  A cool season desirable grass - thrives in Spring and Fall 
- ###  Low shade tolerance 
- ###  Has a deep emerald/blue color which makes it so desirable for lawns 
- ###  Requires a lot of maintenance so is usually blended with other grass seed varieties. Kentucky Blue Grass generally requires about an inch of water per week.
