I have someone in S Florida with a very small backyard that thinks he wants a variety of Zoysia called Zeon (he actually just wants a golf course backyard). I don't see many people selling this variety and actually haven't found it yet in S Florida. His contention for wanting this variety is that it has a fine texture and is shade tolerant. His backyard only gets about 1-2 hours of direct sunlight and 4-5 hours of indirect sunlight through tall, very well trimmed Live Oak trees. The rest of the time, it's in the shade of his townhouse.
With that little light, almost any grass is going to have trouble growing (right now it's just weeds). I'm not sure what to recommend at this point. Any ideas?
