In landscaping, there are a variety of tips and tricks to growing and maintaining a lush green lawn in a dry climate, but in reality, most of the work goes into choosing the right type of grass. With over 10,000 different species of plants in the poaceae family of grasses, selecting the right type can be a bewildering experience. Grasses can be found all around the world in a variety of different climates, but only a few are suitable for landscaping in drier areas. Responsiveness to droughts is, ultimately, the biggest deciding factor that determines how a given species will handle dry climates. Luckily there are only two broad categories to consider.
These grasses can survive a drought or two, or can otherwise grow in a dry climate, but they will not thrive there. Cherokee sedge, known formally as carex cherokeensis, can survive in dry conditions and short periods of drought. This species can thrive anywhere from hardiness zone six to nine, and are typically used in areas that fluctuate between very dry and wet. Grasses such as stenotaphrum secundatum and paspalum notatum, known more commonly as st. augistine and bahia grass, respectively, are truly drought-tolerant and will only be found in hardiness zones on the dry side of eight to ten or eleven, but unlike the cherokee sedge, they do not thrive in really wet or really dry soil.
Some grasses native to dry and arid regions don't just survive and grow there, but are capable of thriving in limited water conditions. Zoysia grass, which is both the scientific genus and common name, thrive in all but the wettest and coldest climates. From regions as cold as zone five, to regions as hot as zone eleven, zoysia grass are unmatched in terms of versatility. Other grasses such as sorghastrum nutans and bouteloua dactyloides, known commonly as indian and buffalo grass, respectively, can also survive long droughts and thrive in dry climates, but both prefer consistent weather whereas the zoysia is considered more adaptable.Ornamental grasses are low-maintenance. additionally, varieties are relatively drought tolerant. Ornamental grass provides visual interest to your landscape in all seasons.
