At maturity, the typical Common Spikerush (Palustris) will reach up to 1.3 foot high, with a maximum height at 20 years of 0 inches.

The Common Spikerush (Palustris) is easily found in nurseries, garden stores and other plant dealers and distributors. It can be propagated by 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 -38°F. has low tolerance to drought and restricted water conditions.
