This cultivar is hardier than the species, and can be grown from Z2 to Z7.
This is a cool-season grass, so it emerges from dormancy earlier than most in the spring, and it blooms in late spring (June here). The flowers can last most of the summer.
The species grows in moist soil, and it can grow in poorly drained areas, though it is also fairly tolerant of drought. It is evergreen in mild winter climates, but tardily deciduous here in Boston Z6a.
It is also one of the most shade tolerant of true grasses---mine did well and bloomed well in dappled shade with almost no direct sun, here in Boston Z6a. Looks great when backlit.
It is not long-lived---mine lasted about 5 years. Regular division may help you keep it going longer.
