‘Overdam’ Feather Reed Grass Calamagrostis acutiflora
Overdam is cool-season grass. Cool-season grasses put on most of their growth in spring before temperatures begin exceeding 75 degrees Fahrenheit and in the fall when temperatures cool down. They generally maintain good color through the summer but won’t grow much when it is hot.
Cut back cool season grasses in very early spring.
Cool season grasses tend to look good even as the weather cools. Leave their foliage in place until spring and then as soon as the snow is gone cut them back. Leave about 1/3 of the plant in place. Trimming cool season grasses too harshly can irreparably harm the plant.
Divide cool season grasses in spring or early fall. Cool season grasses are actively growing in spring and fall. These grasses can be transplanted at either time of the year but early spring is probably the best time to divide. If you do divide them in the fall, be careful that the freeze/thaw cycles of winter don’t heave the plants out of the ground, this happened to a couple of my coral bells last winter.
Cut clumps of grass to the ground in late winter before new shoots appear.

Overdam Feather Reed Grass Info
What is Overdam feather reed grass? It’s a variegated variety of feather reed grass, a very popular cool season ornamental grass. It’s a naturally occurring hybrid between Asian and European species of grass. It is hardy in USDA zones 4 through 9. The plant grows quickly, with its foliage usually reaching 1.5 to 2 feet (.46 to .60 m.) in both height and spread.
In the summer, it puts up stunning flower and seed plumes that are golden in color and can reach 6 feet (1.8 m.) in height. The seeds are sterile, so there’s no danger of unwanted self-seeding and spreading. Its foliage is bright to light green, with borders that are white to cream colored.
It grows in a clumping pattern and looks especially nice in garden beds as a backdrop to flowering perennials where it provides interesting shades of green and white in the spring, and stunning height, texture, and color with its flower and seed stalks in the summer.
