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.
