ALKALI SACATON FACT SHEET

Summary

Alkali Sacaton is a tough perennial native grass that is highly tolerant to drought, alkali, and saline soils. It occurs in all the western states and isolated areas in the eastern part of the U.S. Although it is very alkaline and saline tolerant it also does very well in fertile soils. The seed is very small and must be planted shallow to acquire a good stand. Frequent irrigation is required for adequate germination, however once established it can thrive in environments with less than 15 inches annual rainfall. Alkali Sacaton is generally found growing in alkaline flats, prairies, and sandy plateaus. Mature plants reach 24 to 42 inches in height and when mature have red-colored seedheads.
