Alkali Sacaton (Sporobolus airoides)

A Resilient Native Grass for Tough Landscapes

Overview

Alkali Sacaton (Sporobolus airoides) is a tough, warm-season perennial bunchgrass that grows naturally in the western parts of North America. It is known for surviving harsh environments, making it perfect for dry landscapes, restoration areas, and places with poor soil.

This grass not only tolerates drought but also grows in a wide range of soils, including sandy, salty, and clay-rich types. Furthermore, it can handle both seasonal flooding and dry spells once established. As a result, it is highly valued in native gardens, rock gardens, and erosion-prone areas.

In addition to its resilience, Alkali Sacaton is very low maintenance. It resists most pests and diseases and is also deer-resistant, which makes it even easier to grow.
