Green Alder is a native, cold-hardy shrub found in boreal forests, along slopes, and in open upland habitats. It fixes nitrogen in the soil, improving fertility and helping other plants grow, while its roots help stabilize slopes and disturbed ground. Fast to establish on poor soils, it is widely used in reclamation, restoration, and erosion control projects.

With its smooth grey bark and shiny green leaves, Green Alder often forms dense thickets that provide cover for birds and small mammals. Its seeds, buds, and catkins also supply food for wildlife. Green Alder is well suited for naturalization and ecological restoration.

Note: We use Green Alder for Alnus alnobetula subsp. crispa. This species is also known by many other common names, including Mountain Alder, Sitka Alder, and others. Please confirm the scientific name to ensure you are ordering the correct plant.

Mock Orange is an ornamental shrub known for its fragrant, white flowers. The scent is often described as orange-like with a hint of jasmine. Attractive to pollinators, hummingbirds, and humans alike.

Mock Orange is highly versatile, and can be used as an ornamental shrub, either alone or as a hedge. It is well suited for streambank stabilization and riparian zone restoration, due to its ability to grow in low, moist areas as well as those that are high and dry. Lewis Mock Orange also has the capability of being used in soil bioengineering projects such as live staking.
