Pygmy Caragana
Sitka Alder

Pygmy Caragana is a shrub that is related to Common Caragana and has a compact size that is suitable for yards with limited space. Its size is perfect for landscaping and decorative hedges, and requires little maintenance. This nitrogen fixer has fine-textured foliage and small yellow flowers. Much like Common Caragana, it is hardy and drought tolerant.

Popular as a low maintenance commercial landscaping shrub and for hedging. This species does have tiny spines that might poke you a bit. It has a nice appealing texture when mature.

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.
