Digby’s Top 5 Hedging & Screening Plants…
#1. Adenanthos sericeus – Woolly Bush
This very tactile bush provides soft, velvety grey-green foliage to the ground. Adaptable plant for a wide range of soil types, for planting in both sun or shade that can be pruned for more formal hedging styles or left to grow more freely if you’re after a less stylised feel for your garden. This upright plant with delightfully silky, silvery foliage makes a very useful screening plant, cut foliage for arrangements and even an Australian native Christmas tree.

#2. Hakea laurina – Pincushion Hakea
A hardy dense foliaged plant can grow 3-6metres high and 2-5 metres wide – and with masses of delightful globular red and cream flowers in autumn and winter – it makes for a pretty hedging plant. They’re prolific at attracting birds, and other insects too. Plant it in a sunny spot to ensure best flowering that begins with buds in late summer. A shadier spot means less flowers and with shallow roots be mindful of windy weather. Frost tolerant, but take care of new growth.

#3. Grevillea ‘Robyn Gordon’
What’s not to love about one of the most popular grevilleas – it flowers all year round, attracts birds and is happy in a wide range of soil types and climates. It’s growth is compact so perfect for a low hedging effect. Keep trimming off spent flowers and feed in spring with a good native fertilizer to keep this otherwise low maintenance plant in top shape. Try it in full sun or light shade, and mass plant to ensure to help create the desired hedging effect.
#4. Pimelea ferruginea ‘Magenta Mist’
The classic mounded shape of this plant makes it ideal for more formal gardens and low hedging, particularly in coastal areas. Bright pink flowers in spring will create an almost carpet like effect planted en masse. Be sure to feed with a good native fertiliser and prune after flowering to encourage dense growth.
#5. Grevillea preissii
A hardy plant for low growing hedging and can be pruned readily to offer more formal hedging effect. Red flowers provide winter and spring colour in your garden.
