Australian Silver Oak (Grevillea robusta) Tree

Australian Silver Oak (Grevillea robusta) Tree - Ornamental Trees. The Australian Silver Oak botanically belongs to the Proteas (Proteaceae) family. It is native to parts of the east coast of Australia. It is an evergreen tree, large in size, with a height of up to about 50 m. It has a fast growth rate, an upright habit, a pyramidal-oval shape and medium-dense canopy. The leaves are odd compound pinnately, smooth, green, lanceolate, with revolute, parted margins. The impressive flowering of the tree occurs from early spring to early summer. The fragrant, monoecious flowers are orange-yellow in colour and tubular in shape, borne on spike inflorescences. The Australian Silver Oak is a fairly easy-to-grow tree. It can be planted in a variety of outdoor environments as it tolerates relatively low temperatures well, quite a bit of drought, and adapts to almost any soil type as long as it has excellent drainage. It can be used both in gardening and in landscape architecture, planted alone as a plant of special beauty, in groups and also in compositions with other plants. Thanks to its resistance to salt spray, it can even be planted in coastal gardens.

Notes:
The Grevillea robusta is a potentially invasive species and may behave as a difficult-to-exclude weed. For this reason it should not be planted outside urban areas.

► It is offered at a price determined by the particular characteristics of the tree, such as the size of the pot, its height, and age. Large trees are also available for sale (and planting) upon prior arrangement. In any case, the price or prices listed are indicative.
