Pearl grass looks like cow grass but they have shorter, rounder and thicker leaves. Instead of the grass blade that stands up, pearl grass grows sideways and lie flat against the ground.  They need more water compared to cow grass to do well and are less hardy. Growth rates are much slower and they grow well with some shade and not under direct sun the whole day. Under direct sun, they require frequent watering otherwise the edges of the grass blade starts to turn brown. Pearl grass do well in sandy and well drained soil. If your garden is water logged after heavy rain, they tend to get infected with fungus and dies off. The advantage of pearl grass is also its main disadvantage. They grow slowly so mowing is almost never required. However because they grow so slowly, other seeds blown into your garden can take root easily. While you won’t need to mow them, you have to weed more often to get of any wild grass that grow in your garden. Wild grass and weeds can easily overtake pearl grass if you don’t weed your garden regularly.
