'Overdam' has variegated foliage that starts out with bright creamy-white margins which then fade to white with a pink flush. The upright clump of foliage will remain under 2' tall. In late spring, strikingly erect, feathery plumes with sand-colored seed heads appear, reaching up to 5' tall. 'Overdam' is an ideal backdrop for low-growing, flowering perennials all through the year.

100-200 ppm N at each irrigation.
Vernalization:
Cold required for 10-12 weeks at temperatures below 40 degrees F.
Pests & Diseases:
Avoid growing too wet as this can lead to crown and root rots.
Potting & Timing:
Calamagrostis is a cool season grass, meaning it begins to grow as soon as the temperature rises above freezing in the spring. Best planting times are in the spring and early fall.
NOTE: Calamagrostis brachytricha is a warm season grass and should only be planted when temperatures are 68 degrees or warmer. Plant these in early summer for best results.
Moisture:
Use a well drained media. Keep moderately moist.
Planting Level:
Plant the crown level with the soil line.
Lighting:
Requires long days for flowering.
Other Comments:
This is a cool season, clumping grass with an erect growth habit. It prefers full sun and can tolerate a heavy clay-based soil. It does not re-seed. 'Karl Foerster' was voted Perennial Plant of the Year in 2001.
