Plant Profile – Grevillea Ground covers

Grevilleas are one of the most commonly grown Australian native plants in our gardens and landscapes. Not only are Grevilleas versatile and drought tolerant they come in so many different sizes, shapes and forms including groundcovers, small to large shrubs and trees. In this article I will touch on some of the most popular ground cover types for around Australia. In general the following Grevilleas will grow Australia wide but some varieties are more frequently grown in different parts of Australia.

The 2 most popular cultivars for more humid areas including NSW & QLD would have to be Grevillea ‘Bronze Rambler’ and Grevillea ‘Poorinda Royal Mantle’ both hybrid Grevillea cultivars. ‘Bronze Rambler’ has bronze to red new growth and red toothbrush flowers throughout the year. ‘Bronze Rambler’ has a vigorous nature and is a very hardy plant for difficult sites. Spreading up to 4m across it is very useful for rapidly covering large areas or banks and batters.

‘Poorinda Royal Mantle’ is ideal for the same uses growing with a spread of 3m or more and responding very well to pruning. This plant has lush foliage with coppery red new growth and typical red coloured toothbrush flowers. Both ‘Bronze Rambler’ and ‘Poorinda Royal Mantle’ grow and perform well not only in humid areas but right across Australia; they are definately an all round good performer.

The following varieties are more commonly found to be grown in the cooler parts of Australia including WA, SA, TAS, VIC, ACT and NSW.
Grevillea juniperina prostrate forms are hardy and adaptable varieties which perform well in drought and frost. This species is quite variable and some selections are better than others. A particularly hardy and showy form is the cultivar known as ‘Molonglo’; this is a hybrid between an upright, red-flowered form and a yellow, prostrate form which is quite commonly grown.

Grevillea obtusifolia is a good choice for cooler areas it is vigorous, low growing and has very dense grass like foliage, great for suppressing weed growth. It is excellent for planting out banks and cascading over retaining walls. Grevillea lanigera Mt ‘Tamboritha’ is popular in cultivation and has proven to be hardy in a range of climates provided the soils are well drained. This variety will actually grow as far north as Brisbane. It will get to a spread of approximately 1m and is ideal for rockeries, mass plantings and even grown in a container or feature pot.

Grevillea ‘Gaudi Chaudi’ this is another functional Grevillea groundcover with dense foliage and a large spread. It is tough, low maintenance and good in shade. 'Crimson Villea' is a tough, compact Grevillea with masses of stunning crimson flowers.

As a rule these varieties listed prefer an open sunny position with a free draining soil. They will tolerate part shade and coastal conditions and do respond well to regular pruning. They all have excellent drought and frost tolerance and will produce flowers which have the added bonus of attracting native birds.

There is a lot of breeding happening at the moment with Grevillea ground covers, some are natural selections or natural hybrids and some have been purposely hybridized to create improved characteristics, such as better growth habits, disease tolerance and flowers. In the future I will be featuring some of the new Grevillea ground cover cultivars currently being tested which will definately be worth keeping an eye on.
