My obsession with Breynia ‘Ironstone’

Technically this is Breynia cernua ‘Ironstone Range’ and I absolutely adore it, these images are taken in a friends garden, he is a very talented “master” gardener and treats his Breynia ‘Ironstone’ mean….and it loves him for it 😉

I have written about Breynia ‘Ironstone’ before and have been patiently waiting to photograph a fine specimen like this to sing its praise once more. I am a bit taken with this native shrub for two main reasons the first is its obviously striking foliage and interesting habit.

I love the way it is weeping but the branches are held gracefully horizontal, it really doesn’t look like any other native Australian shrub.

The second reason I encourage every second person to plant it, is its highly contrasting colours, when mixed in with lime greens it makes a fantastic feature shrub.

So apparently the secret to keeping Breynia ‘Ironstone’ looking this lovely is to cut it back hard once a year, and by hard I mean almost down to the ground.

The leaves are quite thin and are prone to looking a little ratty after dry or windy periods, so cutting it back encourages fresh, red new growth. Plant it in part shade in a sheltered position and keep up the water in the drier months and you will be rewarded with a soft, delicate feature shrub to add contrast and interest in your native garden. In the image below you can see a large spun copper dish, cool and enticing for the birds in the Breynia’s shade 😉

    It sure looks nice. But can it become invasive? Do birds eat and spread the berries? Is it in the euphorbia family ?

      Hi Bronwynne,

      Yes it can become a little invasive, the seed is very viable and spreads easily,

      Best Wishes,

    Been growing it in Far North Qld. Yes, it is in the euphorbiaceae family. Haven’t seen it become invasive, though it did send up a few suckers (easily controlled). Also attracts the common grass yellow butterfly which look great contrasted against the purple. Caterpillars will defoliate the shrub if enough of them but a pruning once the caterpillars are gone will do wonders. Not very long lived I think but luckily grows easily from cuttings.

    What is the best time of year to cut back your Breynia ironstone?

    • Kath Gadd on

      Hi Gena,

      You can prune back your Breynia in late Autumn to early winter, then you should get a good flush of new growth for the warmer months, don’t hesitate to give it a generous cut back too, they quite like it!

      Best Wishes,

    I love these too, and have a few in my backyard in Brisbane, but one of them is suffering a bit and I’m thinking of digging it up and moving it, as I think it needs more sun. How do they respond to transplanting?

      Did you find out the answer to the question about transplanting. I have one near a pile of trees I gave to burn and I don’t want to lose it. I have them in my forest but feel they are so precious

        Hi Wendy,

        This plant reseeds very easily so I think it should be fairly hardy to transplant, however that depends how long it has been in the ground for? if it is under a year I would give it a go.

        Good Luck!

    I’m in the dry tropics (Townsville), considering using it as a formal hedge which is something it’s supposedly recommended for … But looking at these comments and at three plant itself which has a more “open/spreading ” habit, I’m not certain it will be suitable. Thoughts?

    • Kath Gadd on

      Hi Jo,

      I’m not sure of its suitability as a hedge, when I grow it here in the Sydney region it can become quite sparse in the winter and if its particularly dry. It loves being pruned though, and perhaps as your climate is warmer it might be ok?

      Best Wishes,

      hi Jo. this photo is my former tree on Magnetic Island. I never ever pruned it. It provided a reasonable screen, as you can see. This tree was completely severed at the base by a strong wind, twice, and simply grew back. The plant will go into a sprouting frenzy if the roots are cut. The roots appear to spread quite wide in distance. My neighbour decided to pave their property to the fence and possibly they cut the root, causing it to sprout through their pavers. Unfortunately, I decided to remove the tree, for their sake, which was very sad, given it was one of my most beautiful trees. Also, it was near my main water pipe so I was concerned. https://imgur.com/Eb70BKW

    Hi I have a Breynia Ironstone that is suddenly losing its leaves, what is wrong?

    • Kath Gadd on

      Hi Vanessa,

      Breynia ‘Ironstone’ can drop leaves when there is a cold change in the weather or an exceptionally dry or windy period, could that be what is affecting it?

      Best Wishes,

      Kath
