Blue Grama Grass
Smooth Sumac

Blue Grama is a native perennial bunchgrass recognized for its blue-green blades and unique seed heads. They grow along one side of the stem and are often compared to eyelashes, eyebrows, or mosquito larvae, which inspired its common names, Eyelash Grass and Mosquito Grass. As the seed heads begin to dry in the fall, they curl, further enhancing the plant’s distinctive appearance. The seeds provide food for birds, and the grass serves as a host plant for certain species of skipper butterflies.

As a warm-season grass, Blue Grama has a slow start in spring and does not actively grow until soil temperatures rise. Its deep roots help with erosion control, and the grass is drought-tolerant once established, thriving even in poor or alkaline soils. It is well-suited for soil stabilization, naturalization, restoration projects, or as an ornamental accent in gardens and landscapes.

Smooth Sumac is an excellent shrub for both its ornamental appeal and tolerance of difficult planting sites. You'll love the attractive pyramidal spikes of hairy, red berries that emerge on female plants and the fern-like foliage that covers both male and female varieties.

Ensure you give Smooth Sumac enough space to spread out due to its high suckering nature. While not ideal for small, urban yards, this shrub will make a stunning border along a woodland edge or roadside.

Note:These plants typically reach maturity and make their sex easily known (females producing fruit) in their 3rd or 4th year of growth. Our seedlings are too young to identify their sex.
