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.

European Hazelnut is a large shrub that is native to Europe. It is known for its edible nuts that ripen in late summer to early fall. The nuts can be eaten raw or roasted and have a sweet, earthy flavour. Nut production can start as early as 2-3 years but typically takes until at least 4 years for significant yields.

Catkins appear in late winter to early spring and as they release pollen it attracts bees and other pollinators. Since male and female flowers bloom at different times, multiple shrubs will have to be planted for cross pollination. It is recommended to plant European Hazelnut with other hazelnut varieties such as Beaked Hazelnut, Frank, Yamhill, and York. Planting with other varieties will increase nut production.
