Eucalyptus curtisii

Post by Rory »

Eucalyptus curtisii is one of the greatest choices of native material for bonsai.

It tolerates all sun/shade conditions. But it grows very slowly in strong shade.
It is very hardy, and isn't badly affected by myrtle rust.
It is an excellent choice for all stages of enthusiasts. It shoots back right along the trunk after a trunk chop. It's leaves reduce very well if you occasionally keep up the pruning.
It is the equivalent replacement of a Japanese maple for Australia in my opinion. The new leaves stay. Eautifukly red/pink for quite a few weeks. The new shoots stat red for months.
It tolerates drought and over watering very well. It grows fast or slow depending on the levels of sun.
It produces a naturally gnarly trunk over time, and continuously produces new shoots all over.
You can cut back the roots heavily and it will recover, usually with serious gusto.

I think of all the eucalyptus I have tried, this one is certainly one of the greatest all rounders.
The only species better, would probably be the naturally smaller leaf varieties, but I find they aren't has hardy as the larger leaf varieties. Eucalyptus crebra would probably be on par with curtisii.

Great start you've got there Rory! How long have you been growing those little guys.

Is this species prone to dropping branches/dieback like some of our other natives?

I don't trust Bonsai, they are a little shady.

I'm glad to read this Rory, @Redsonic alerted me to this euc last year, when I bought one for her at a Native Plant market, and I've since bought some tube stock to be going on with.

Looking forward to seeing how yours go.

A good-looking Euc.- is it frost-tender? We've just had the nastiest winter I've seen in 7 years.

Apparently not. A quote from the Australian National Botanic Gardens website
Myrtaceae, the family to which Eucalypts belong, is a group of very attractive, adaptable and hardy plants suitable for cultivation in a wide range of situations. E. curtisii has proved to be frost resistant and easily cultivated in the Canberra climate.

Ive only been growing these for a few years now, so about 10-15 more years to go before they look any good in my opinion. But I am tempted to try one as shohin.

Well.... I guess I'll let you know in time. This would be no different to exotics, with their die-back though.

Hello Anthony,

I'm so sorry mate, I wish I could.
But I've only been serisously growing eucalyptus for about 4-5 years now. I had some reasonable material a long time ago but they died when I was on a balcony and were left without water over a bad summer.
I don't have any worth showing.

In about 5-10 years I should have some pretty good natural-styled material to display.

In the mean time take a look at some of the trees by Peterh. He has a beautiful eucalyptus nicholii I think it was.

Or take a look at the Canberra bonsai society annual bonsai shows. Just google it and you can browse some beautiful specimens there.

All the eucalyptus I'm growing are a delight to work with, and I'd highly recommend them over all exotics, any day.
Just don't bother with the species that have really large leaves. You can't maintain good proportions on them.
Rory

Thanks for the reply Rory...sorry to hear about your potential beauties,very good that your still persisting with these/other species,like your passion...hey hey whew back on the exotics lol ....but they don t come even close to my figs and pines/exotics and other guys exotics :2c: ,sorry about that chief..but you got start some where and your enthusiasm is great and documentation of growing habit is vital if people are to try and help you promote.. well done.

Yes Peter and Mr Fletcher from Tasmania have a few that certainly jump out of the box...very,very nice.

cheers Anthony

He you go Rory,maybe you can help me identify this species,
.
Took this from a flat rock where I was working,it was growing on a flat rock in a slight crease(no fissure to secure it,obvious picking up silt and extra water due to position)in a palm full of very damp moss,there was alot of heavy rain on off over a month in late Autumn...amazing,I don t believe it would have survived summer...anyway lets learn.

Had about 4 leaves one stem,hardly worth it,but it hung in there over winter and here is today.

I have noted it does grow back on bare wood after it has hardened off after chopping...I think best to nip every other terminal so energy does not miss the desired area(like a fig)...good start.

Leaves are not too bad a size when matured off..very handy..I believe would suit a good medium size tree up for that leaf.

Do not let it remotely dry out,it drops its leaves from shock.then we know whats happens then.,if we completely miss the ball..phew..mix is all organic with moss and a coat of scoria to hold moisture

Now testing it when the new leaf/bud starts to form bit like a maple if you like for tighter internodes.

So many questions to ask..but we will have a go..hope you don t mind me posting here...as for design another day nothing to use yet ...cheers

Hello Anthony,

You may have a little Angophora costata, a bit hard to see the leaf structure from here, it does appear to have some leaves which are emerging as opposites from the main stem.
It's only a guess, it's only a little tree and there are so many species to chose from.
The rock you mentioned where you located the tree - was it Sandstone?

Edit: Just adding this link FYI:

Hi Anthony,

You'll be fishing the dark for identification. I have many eucalyptus and angophora that I have no idea what they are.
I wouldn't worry about an ID unless in ten years it becomes something worthwhile knowing.
Generally most eucalypts can be grown with the same techniques.
If you're wanting a bigger trunk though, I'd get it out of that little bonsai pot and into a big growing container though.

All eucalyptus hate to be 'constantly' pruned. They can suffer die back as a result.
They should be repotted safely anywhere from about October though to march.

On your tiny specimen there you probably won't see the full mature leaves until it's allowed to fro uncut for a few seasons. (If you're interested that is)

Thanks dansai. I may have access to seeds, but not the aptitude. And, increasingly clearly, not enough time.

Thanks for starting this post, and the information on E. curtisii Rory. As Melbrackstone said, I "discovered" this tree earlier this year when I was walking the dog and found a beautiful small euc with lovely bark growing in a park in a suburb I rarely visit. It was a multi-trunk tree, which is apparently one of the ways they can grow. Otherwise known as a Plunkett Mallee, their natural range is restricted to the Brisbane area. I collected seed from the tree at the time, but didn't have any luck with germination. I plan to go back this summer and grab some fresher seed and try again. In the meantime, I have one seedling that Melbrackstone found for me and have been reassured by your post that it may make a good bonsai one day.
