Where to Plant

Dallas Blues Switchgrass is best planted in an area with full sun exposure. Ideal for open landscapes, it can also thrive in garden beds or as a striking element in mixed borders.


This grass requires full sun to perform best, enjoying at least six hours of direct sunlight daily.


It adapts to a wide range of soil types but prefers well-draining soil. Tolerant of both dry and moist conditions, it’s versatile in various landscapes.
