Very nice focal grass, tall and graceful, great wind action. It is also quite forgiving - the early grass stalks look very similar to my common clumping orchard grass and I diligently pulled them all out one spring. By the time I got to my final clump, I realized my mistake and left that one alone. Mid-summer, I really couldn't tell any difference between the clumps I had massacred and the one I left alone. I have not yet tried to divide this, but plan to this spring when it breaks dormancy.

The Perennial Plant Association's pick of the year for 2001, 'Karl Foerster', is a very upright clump forming grass that is easy to grow in full sun and average soil. Growing 4 to 5 feet tall, it is a cool season grass so it greens up in early spring and by mid-summer has whitish flower heads that mature to warm gold later on. 'Karl Foerster' will bend and sway in wind and rain but will always become upright again.
