Grasses are used most commonly as ornaments in decorating our landscape. They're unique in that they are standalone bushes and offer a good accent to most gardens. There aer many varieties of grasses.
There are 2 types of grasses:
Cool Season Grasses Cool season grass will start to grow early in the spring and may even remain semi-evergreen over the winter. Cool season grasses also seem to do better and have better foliage quality when temperatures are cool or if they are given sufficient water during drought periods. If they are not watered during drought, they tend to go dormant resulting in brown foliage.
Warm Season Grasses Warm season grasses will do better during warmer times of the year and remain good looking even when temperatures are high and moisture is limited. Warm season grasses do not begin to show growth until the weather becomes stable and the soils warm.
