Hakea nodosa, Yellow Hakea, is a shrub reaching a height of two metres.
Leaves are up to five centimetres long, light green, usually needle-like but sometimes flattened. Yellow flowers are carried in clusters in the leaf axils. They clothe the branches from May to August. The fruits, that follow the flowers, are said to come in two forms often on same plant. One type has a smooth surface that open when mature. The other type is woody, remaining on the plant and has warty lumps on the surface. The fruits are dimorphic meaning having two forms.
We have never observed two fruit types in our cold climate garden. Our specimens always have “conventional” woody, persistent fruit.
Hakea nodosa occurs in south-eastern South Australia, Victoria and Tasmania. The species is one of the dominant understorey shrubs in many bushland areas in Tasmania.
We have successfully propagated Hakea nodosa from cuttings as well as seeds.
The species name means knotty or gnarled referring to the fruit.
