Yellow Mountain Avens

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.

Yellow Mountain Avens is a native perennial wildflower with bright yellow buttercup-like blooms. The nectar-rich flowers attract a variety of pollinators, including bees and butterflies. By thriving at higher elevations, it helps sustain pollinator populations and provides one of the earliest sources of nectar and pollen in alpine habitats. After the blooms fade, the plant produces silky seed heads that begin as upright, compact tufts and gradually expand into rounded, fluffy clusters, adding texture and interest to the landscape.

As a nitrogen-fixing plant, Yellow Mountain Avens enriches soil fertility and supports the growth of surrounding vegetation. It forms dense, spreading mats of evergreen foliage that act as a groundcover and help stabilize soil. Often among the first species to establish in disturbed alpine sites such as glacial outwash or landslides, it is well-suited for alpine revegetation, erosion control, naturalization, and ecological restoration projects in harsh, rocky environments.
