Banksia robur - Strong Banksia - 10 seeds


Banksia robur is an attractive shrub type Banksia growing in its native habitat to a maximum of 3m tall.  The leaves are large, striking and robust, a deep green, with slightly serrated edges, flowers are long and cylindrical, a deep luminescent metallic green turning more golden with age and maturity, and appear from Summer to Winter. 


The fruit is cone shaped and compact and new growth is velvety reddish brown, the blooms make an unusual and attractive cut flower, particularly when young.  It is slow-growing and long-lived.

The natural habitat of this Banksia is the east coast of Australia, variously between Cooktown in northern Queensland and Wollongong in New South Australia where it inhabits low woodland and sedge-heathland on sandy or peaty sand, often swampy, with an annual rainfall of 800-1000mm. 


This species is at home with high humidity, although not under threat in the wild, significant areas of its habitat are coming under increased pressure through urban development, particularly in south east Queensland and New South Wales.  It is now widely cultivated as a no-nonsense landscaping and revegetation species.

Propagation is from seed which should be sown into a standard seed raising mix and watered as required.  Plant young seedlings as soon as practical to avoid too much root disturbance, plant into well drained soil with an acidic pH of around 6.0 to 6.5.  Phosphorus fertilisers are toxic to the plant as it can take up even the smallest traces of this element. 


This species is lignotuberous and can be pruned heavily once established, although not on the trunk which is the source of new growth.  This is one of the few frost tolerant Banksias, it can be planted out in full sun or light shade in light to heavy soil.
