Bluebunch Wheatgrass is a native perennial bunchgrass common across prairies, foothills, and open woodlands. Longer-lived than many other grass species, it develops deep, fibrous roots that stabilize soils and make it drought-tolerant once established. It is a cool-season grass, growing most actively in spring and fall and slowing during the heat of summer.

This hardy grass provides excellent forage for deer, elk, and bighorn sheep, and is especially palatable to livestock. Its seeds feed birds and small mammals, while its bunching growth offers protective cover for ground-nesting birds such as sparrows and sage-grouse, as well as shelter for small mammals. Bluebunch Wheatgrass is well-suited to rangeland & prairie restoration, naturalization, and erosion control projects.

Blue Flax is a native perennial wildflower known for its blue to violet flowers. Each flower lasts just a single day, but new blooms appear continuously, providing weeks of colour. This extended flowering period provides a reliable display from late spring into summer and attracts a variety of pollinators.

They can self-seed readily, so removing spent blooms helps manage their spread. Birds feed on the seeds, and when cooked, they are edible and are described as having a mild, nutty flavour. The plant grows in loose clumps with slender stems and fine foliage. Young plants are leafy, but as they mature, most leaves are shed.

Blue Flax grows well in a wide range of soils, including poor or sandy conditions, and is drought-tolerant once established. The deep root system helps to stabilize soil and prevent erosion. They are well-suited for pollinator gardens, restoration, naturalization, and xeriscaping projects.
