Zoysia is one of the most hardy grass
plants there is, Longy is right, dang near bullet proof, it will grow back. While zoysia is extremely drought tolorant it will take over watering for a while with little to no problems, however it will thin it out over a long period of time.
Personally I hate the stuff, and most people up here in the north grow to hate it too, after a couple of years of having it.
In this
zone it is the last grass to green up in the
spring, and the first to go brown in the fall.
