Conditions Comments: turf grass, more so than Buffalograss. Can survive with as little as 7 inches of rain annually. The drier it is, the less likely it will be to form a solid mat by rhizomes; it will stay in separate clumps. For this reason, it is often mixed with Buffalograss and/or wildflowers for a solid cover. The taller you let it grow, the less water it will need, because its roots will be shaded.
