If this stuff is doing well in the shade that narrows it down to St Augustine and one of the rare zoysias that survive in shade. Since it is a coarser blade than bermuda, it still could be either grass. There are two problems with being more certain. St Aug has a boat shaped blade tip and St Aug spreads by sending runners over the ground, not under. This grass clearly is spreading underground. I'm going with zoysia. Not very many of the zoysias will survive in the shade. This might be one of them.

If you want a pretty sure bet for a shady area grass, get a flat of St Augustine and lay it back in there. Water it daily to keep the sod moist, not soggy. In a couple weeks it should knit into the soil and start to spread. St Aug will spread 5 feet in all directions in the spring and again in the fall. One flat will cover a lot of ground in two years.

Actually most of the yard is SA- most of the yard is in shade. This gets the most sun and thus the driest. I thought about zoysia but was not sure, it is rare around here. This grows much slower in height than the SA too so maybe it is zoysia. It seems to get enough sun, enough to have a slight cushion effect at that. I will probably get some SA though since it is easily available.

Are you in north Los Angeles or north Louisiana (or north Lake Arrowhead)?

I'm in north Louisiana- the abbreviation for Louisiana is LA. I don't think there is an abbreviation for Los Angeles. Sorry just checked back here again. It might very well be zoysia since I see that is can tolerate some shade. This gets quit a bit of sun though. I think plugging some SA would be the best.

If you are in Louisiana then that must be zoysia.

LA is commonly used for Los Angeles, too. I see it all the time in the forums - especially since the population of Los Angeles is much higher than the population of Louisiana.

True that is, but I always think if everyone can use their official abbreviation I should be able too. Colloquial language often does specify LA for Los Angeles though, but it is really not accurate.

Seeing how the city of LA has almost as many residents of the state of LA, I would say most people could easily confuse the two based on which side of the Mississippi you are on.

Lets let Google solve this for us! :)

You know it really doesn't matter what the population is, the official postal abbreviation for Louisiana is LA. Please tell me what the postal designation is for Los Angeles. Really, you're being a bit over the top with this.

Looks similiar to our Meyer Zoysia

Is the population of Los Angeles really more than the whole state of Louisiana? Hard to imagine...
