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.

This European species is a very reliable and easy grass perennial to grow. It is a cool season grass that begins growth early in spring. It has a very erect, neat habit and is soft to touch. It blooms in July and early August and then its pinkish-tan grass flower spikes become more narrow as the flowers are replaced with seedheads. It is very easy to dig up and divide for propagation. I can't think of this grass species really having the center of the clump die out as many clump grass species do after 5 to 15 years. My plant at the front door porch area has not needed division for 16 years. It looks good all winter long, then I cut it down in before growth in March. My specimen is now in part shade because the trees have grown much larger, but when the sun hits the plant it really looks scenic. (What can be good about plants in part-shade is that they don't get so huge and thick as in full sun.) "My plant is the cultivar of 'Karl Foerster' that bears more pinkish grass flowers than the mother species and is the most common cultivar that is sold at most conventional nurseries, and is common in gardens and used a fair amount by landscape designers.
