A gardener trimming a hedge - these are some of the best hedging plants

Part 4 of our guide to the best hedging plants continues where it left off – with Lilly Pillies.

Lilly pilly Cascade (pbr) tall hedge shrub plant

If you would like to create an informal style hedge or screen (limited or no pruning), then have a look at Lilly pilly Syzygium “Cascade” (pbr).   

Lilly pilly “Cascade” has beautiful weeping foliage and a nice bushy habit, which make it quite an interesting screen plant or hedge.  Syzygium “Cascade normally only grows to around 3m, however it can grow taller. 

The foliage on this plant is light green and the new growth is pink. Not only does it have pink new foliage, it has pink flowers in spring or summer, followed by pink fruit (berries).  Lilly Pilly “Cascade” is all about the colour pink.  

In regard to pruning, this plant responds well to a light cut back,  however it generally does not need pruning like other hedge plants.  It has a natural weeping habit which means that it looks and grows quite well without pruning.  If you do need to give it a prune … go for it, as it will regenerate in a few months and go back to the way it was, with nice weeping foliage again. 

The rate of growth of this plant is medium to fast.  Best light conditions for this plant are full sun to semi-shade.   Best soil conditions are any well drained soil, this plant is not too fussy about soils and will generally grow in most soils. 

Best climates are subtropical, temperate and warm temperate regions.  “Cascade” is an Australian native plant.

Lilly pilly “Resilience” tall hedge & screen shrub

Next on our list of the best hedging plants is the Lilly Pilly “Resilience”.
