Tall Manna Grass
Yellow Mountain Avens

Manna Grass and other waterside plants are an excellent way to prevent erosion and provide habitat and forage for animals. The difference is that Manna Grass looks better doing it! With distinctive purple grains at the top of its stalks, Manna Grass adds a splash of color to the waterside that most other aquatics can't offer.

Manna Grass is good for returning disturbed sites to nature and provides nourishment to many animals, except for cattle who find it toxic.

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.
