Sitka Alder
Witch Hazel

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.

Witch Hazel is a deciduous shrub, or small tree, with a short trunk, bearing numerous spreading, crooked branches.

The seeds grow in a long, wooden pod with two to four seeds per pod. Upon ripening, the pods burst, firing the seeds up to 30km an hour.

The leaf and bark extract of Witch Hazel has been used as a remedy to common ailments such as inflammation, bruises and much more for many centuries.
