Acacia diphylla: is known as the Gorge Wattle because one of its strongholds is in the gorge country, east of Armidale in Northern New South Wales. There is another occurrence further east near the town of Gloucester.Plants
Botanically the Gorge Wattle is now classified as a subspecies of Acacia blakei. Horticulturally we prefer to keep the old name for this splendid wattle.
Acacia diphylla grows into a tall, upright shrub or small tree. The species is unusual in having both juvenile and adult phyllodes. (In our opinion this characteristic sets it apart from Acacia blakei.) Adult phyllodes are large and leathery whilst the juveniles are just as large but soft and shiny. Both types of foliage are very dense. In spring the plants become covered with brilliant yellow rod-shaped flower heads. Both foliage and flowers are attractive features of the Gorge Wattle. The species could be cultivated as a “stand alone” specimen plant, in the larger garden or as an eye-catching component of a shelterbelt or windbreak.
Acacia diphylla is one wattle that does require pruning to maintain its shape and dense foliage. We have a number of specimens that are over ten years old that have never been pruned.
Propagate is usually from seed. We are also experimenting with cuttings.
