Becky, I cannot tell you a whole lot about lava rock, or red rock. I have noticed that numerous homes in TV have what appears to me to be lava rock in their shrub beds. They also have different kinds of gravel. I also received a couple of fliers from landscapers on putting rock in the beds. I know that I like the look, and obviously the durability. I was told though that the porous quality tended to allow thingys to grow in the rock. Maybe some others in TV who have rock could help us both out. I do know that my wife want to do concrete edging around the beds, so that would help contain whatever we use.
