Russian Olive
Discovery Japanese Elm

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.

Discovery Japanese Elm is great for anyone who doesn't have a lot of time to maintain their trees as it doesn't drop many seeds. It has beautiful dark green foliage and is resistant to Dutch Elm Disease. This elm is similar in shape to the American Elm but is roughly 30% smaller. Instead of having an irregular and broad-shaped crown as other Japanese Elms do, the Discovery Japenses Elm has symmetrical branching, an upright growth form, and develops a classic vase-like crown.
