Rose Glow Barberry is a cold hardy, drought tolerant shrub. It has attractive, mottled foliage that ranges from red, pink, green, and white, maturing to deep maroon.

Rose Glow Barberry has sharp thorns, so be careful when you're handling this shrub. These thorns are what make Rose Glow Barberry an excellent hedge plant as they deter rabbit and deer.

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.
