Growing and Maintenance Tips:


Spartina grows best in moist, fertile soil in full sun to partial shade. It is an aggressive grass, spreading by rhizome as well as by seed, not suited to small gardens. It will tolerate less fertile, rocky, dry soils where it will be less aggressive.

Native to Ontario

 Warm Season Grasses: These grasses are much slower starting in the spring. They do not push new growth until temperatures warm in early to midsummer. They flower later in the summer or fall with most blooms remaining into the winter. Most warm season grasses tolerate heat, humidity and drought; some even thrive in these conditions.
