I was asked recently what a suitable screening plant was for a sunny position?
Here are my top 3 ...
1. Best "Grey Foliage screen" Westringia 'Wynyabbie Gem'
"Wynyabbie Gem" is a 1.5m tall x 1.5 m wide bushy shrub native to Australia. It is also know as native rosemary. This hardy shrub features grey/ green fine foliage. Pretty little mauve flowers appear in spring and throughout the year. I think it's a little under-used in today's gardens. There are so many great reasons to grow this screen. Team it with grey, silver and black foliage for a muted modern palette or use it as a back drop in formal gardens.
2. Best "Tough as Boots Screen"- Viburnum tinus.
I rave about this plant allot. It's an old fashioned shrub that can grow over 3m if left unpruned, but easy to maintain at a medium height. Plant viburnum in a row about 1m apart for a brilliant evergreen hedge or screen. The screen can be kept as low or tall as you like. The lush foliage is covered in clusters of white flowers with a flush of pink in spring. People will knock on my door asking "what is that screen?". It always looks lush, even in the hottest of weather.
3.Best "Red Hedge"- Lilly Pillys.
Pop into Serenity Nursery and you will see several varieties of Australian native lilly pilly. The lilly pilly come under three botanical names- Syzygium, Acmena and waterhousea. If you are wanting a taller growing screen plant Lilly Pilly Backyard Bliss. It will grow 2-3m tall with magnificent red new growth. This particular lilly pilly is popular as it is psyllid free- so there will be no dimpled foliage in sight. "Backyard bliss" responds well to pruning and can be pruned to any height.
Hope this will help solves your screening needs...Krystal
