Pearl grass 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 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.
