Round Leaf Hawthorn
Sitka Alder

Getting its name from rounded, toothed leaves, the Round Leaf Hawthorn is a winter hardy shrub that grows small, red, berry-like fruits.

Commonly used for landscaping, this shrub can also be found along stream banks and in wooded areas. Caution is advised when handling the Round Leaf Hawthorn, as it can have sharp thorns approximately 1" long.

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.
