Calamagrostis x acutiflora
'Overdam' - Variegated Reed Grass
This Variegated reed grass shares the versatile qualities of the larger
green form (C. 'Karl Foerster'),
with the additional attribute of shade tolerance. It is very useful
in Japanese gardens where a sense of scale is essential.
The white and green leaves of 'Overdam' and its smaller size make it
more refined than 'Karl Foerster' which in some ways it is more pleasing
than its big brother, Karl. With ample moisture it will do well in full
sun, but likes a little shade in hot climates. Particularly attractive
along a woodland edge.
Excellent cut flower.
Says C.B. in Anchorage, Alaska: "This plant thrives here in my
Zone 3/4 garden!"
