Russian Olive vs Green Alder

Russian Olive is a medium-sized deciduous tree that has attractive silvery coloured foliage with small yellow flowers that emit a fragrant sweet smell.

It is drought and salt tolerant, and works well as a shelterbelt species. Russian Olive can also be used to combat erosion.

Note: although Russian Olive is planted as an attractive boulevard tree in many northern areas, in warmer areas it can invade watersheds and is considered invasive. Please do some research and plant the right tree in the right place.

Green Alder is a native, cold-hardy shrub found in boreal forests, along slopes, and in open upland habitats. It fixes nitrogen in the soil, improving fertility and helping other plants grow, while its roots help stabilize slopes and disturbed ground. Fast to establish on poor soils, it is widely used in reclamation, restoration, and erosion control projects.

With its smooth grey bark and shiny green leaves, Green Alder often forms dense thickets that provide cover for birds and small mammals. Its seeds, buds, and catkins also supply food for wildlife. Green Alder is well suited for naturalization and ecological restoration.

Note: We use Green Alder for Alnus alnobetula subsp. crispa. This species is also known by many other common names, including Mountain Alder, Sitka Alder, and others. Please confirm the scientific name to ensure you are ordering the correct plant.
