Sitka Alder

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 native evergreen shrub found in forests, slopes, and rocky sites. Its greenery adds winter interest and provides cover to wildlife. It is used to provide ground cover, especially under established trees.

It provides shelter for small animals and birds and its inconspicuous flowers support pollinators. It is long-lived and tolerant of a range of conditions, including drought once established.

Falsebox is well suited for naturalisation projects, erosion control, wildlife gardens, and low-maintenance landscapes. It is a practical addition to restoration plantings and mixed shrub communities.
