Armstrong Maple
Russian Olive

The Armstrong Maple has a narrow, upright columnar growth habit. This stunning tree has showy leaves that range from yellow, orange to red in the fall. It is an attractive hybrid of the Red Maple and Silver Maple. It prefers acidic soils and will have some tolerance for drought once mature.

Edward Murray named the Armstrong Maple in 1969 in honor of Oliver M. Freeman of the National Arboretum, who made the first controlled cross between the two species in 1933.

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.
