Sitka Alder
Falsebox

Sitka Alder is a native deciduous shrub or small tree that often forms dense thickets. Its extensive root system stabilizes slopes and streambanks. Nitrogen-fixing capabilities and nutrient-rich leaf litter improve soil fertility, creating better growing conditions for surrounding plants. These qualities make it especially effective in disturbed or erosion-prone sites.

Often found in moist, high-elevation mountain environments, Sitka Alder also enhances habitat by providing cover and structure in both riparian and upland areas. Birds and small mammals utilize it for nesting, and its seeds serve as a food source.

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

Falsebox is a hardy, native evergreen shrub found in forests, rocky slopes, and open woodland sites. Though small and easily overlooked among the leaves, the maroon flowers still supply nectar and pollen for pollinators such as native bees and flies. Blooming in spring, they provide an important early-season food source. Its year-round greenery adds visual interest through the winter.

Falsebox is a low-growing shrub that tolerates a wide range of conditions, including drought once established. It thrives particularly well beneath the shade of mature trees, where few other plants succeed. With its resilience and ecological value, Falsebox is well-suited for naturalization, restoration projects, and diverse landscape plantings.
