Hardenbergia comptoniana

Now that Cockies Tongues is flowering, Hardenbergia comptoniana follows close behind and paints the winter bushland purple. I got home from camping in Cue to find the Hardenbergia that climbs up my garden fence covered in blooms and bees a-buzzing with nectar drinking.

Seed pod cylindrical hard black pod. [1] On hot days the pod will open with an audible pop and the seeds are flung away from the plant.

Each seed has a white, oily aril attached. [2] This attracts ants [1] and they take seeds into the ant nest for storage and later eating. Some seeds will germinate underground and grow into new plants. The ant in this photo (below) is walking past Hemiandra leaves to the ant nest with its prize.

Growth habit climbing shrub

Hardenbergia will grow up anything

Cultivation Easy to grow from seed after soaking in almost boiling water to soften the hard seed coat. [3]

Will grow up a fence as a screening plant.

This photo (above) was taken 4 years ago when you could still see some of the lattice I trained it up (bottom right). Hardenbergia is extremely vigorous and needs pruning a few times a year. The winter flowering period is spectacular, but the branches die back somewhat during summer. It has leaves year round, but it doesn’t look as pretty during this time. In the summer months I prune off dead branches and it starts growing vigorously again as temperatures cool.
