Coast Cockspur Grass (Walteri)

The Coast Cockspur Grass (Walteri) is generally described as an annual graminoid. This is native to the U.S. (United States) has its most active growth period in the summer . The greatest bloom is usually observed in the summer, with fruit and seed production starting in the summer and continuing until fall. Leaves are not retained year to year. The Coast Cockspur Grass (Walteri) has a short life span relative to most other plant species and a moderate growth rate. At maturity, the typical Coast Cockspur Grass (Walteri) will reach up to 6.5 feet high, with a maximum height at 20 years of 0 inches.

The Coast Cockspur Grass (Walteri) is usually not commercially available except under contract. It can be propagated by seed, sprigs. It has a slow ability to spread through seed production and the seedlings have high vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below 32°F. has low tolerance to drought and restricted water conditions.
