Blue Flax

Bluebunch Wheatgrass is a native perennial bunchgrass common across prairies, foothills, and open woodlands. It has a long life span, unlike many other grasses.
This grass competes well with invasive species, has extensive root systems and is drought tolerant. It provides forage for deer, elk, bighorn sheep, and is extremely palatable by livestock. Its seeds are eaten by birds and small mammals, while its dense clumps offer nesting and shelter.

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.

As a perennial, it dies back to the crown each winter, it will regrow from the base in the spring. Avoid disturbing the crown during late winter to ensure healthy growth the following season.
