At maturity, the typical Canadian Rush (Canadensis) will reach up to 3.2 feet high, with a maximum height at 20 years of 0 inches.

The Canadian Rush (Canadensis) is easily found in nurseries, garden stores and other plant dealers and distributors. It can be propagated by bare root, seed, sprigs. It has a moderate ability to spread through seed production and the seedlings have medium vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below -33°F. has none tolerance to drought and restricted water conditions.
