Post Koelreuteria bipinnata time of year again..
Had to take a pic. Funny that on Google images, a few Delonix photo's are included with this tree. Well,I would say its the "Royal Delonix" of fall in temperate climates.

I really liked the idea of growing Koelreuteria trees until I noticed just how weedy K. elegans is in Australia, my in-laws old farm had them everywhere, and the roadsides had infestations of almost pure stands. Some of the locals just thought they were Jacarandas...! Probably not a problem in my colder drier climate, but why take the risk...

Mine does this too, although it does keep some wood. Even through '09/10. Makes a nice foliage plant (but would make a better tree!)

I'd say the leaves of Melia azedarach, which is much hardier, are similar enough (it was what I thought my Kb was when I bought it) if a gaunt bipinnate evergreen is the desired look. Although IIFC didn't you get rid of yours Kev, as it was threatening to take over? Taking advantage of a fair chunk of real estate here released by a fallen 60ft Leyland Cypress this spring I planted one in a sunny corner and it has really motored. It is one I grew from seed collected from a street tree in Madeira a few years ago 'just because they were there' without, at the time, anywhere in mind to plant it. Then fate stepped in. Albeit rather expensively - having a 60ft confer diced and taken away wasn't cheap. :lol:

Yes my Melia azadrach was removed I thought it would struggle in our climate, it did not, it went for the sky with multiple trunks smothering everything in sight.
Ceratonia siliqua is much less rampant, especially after 2010, a tree I think more people in the uk should try this Carob tree with its glossy green leaves and red stems while juvenile looks fab mine are seed grown never seen any for sale here.

I agree. I also raised one from seed but decided it would take too long (!) so I asked Toby at the Palm Centre to import me a biggish one a few years back - they are often sold pollarded like olives in the Med. - and it is doing nicely. Although I have to say the little one has better colour. But a large gnarly old carob tree is a thing of absolute beauty - lots in the Algarve, particularly - and so totally redolent of the Mediterranean. In the last couple of years I have tried to enhance this and planted Pistacia lentiscus, Phillyrea latifolia, Cistus, Chamaerops and a few other Med plants as I extend into my shady 'new bit' at the back of the garden. Although, of course, i don't have the discipline to keep solely to Med plants... :D

Speaking of less usual trees I have a couple of experiments facing their first winter this year - Schinus molle and Camphora cinnamomon. Fingers crossed!

Bit of a thread hijack - sorry Stan!

I'm growing a Koelreuteria paniculata from seed - boy is it slow! That said even as a seedling it is incredibly hardy.

I don’t have koelreuteria bipinnata, but I grow koelreuteria paniculata coral sun outside and it is doing well. It is much happier in the ground than it was in the pot.
In my home town in Bulgaria I have seen koelreuteria planted as street trees but I am not sure which exactly type they are. I remember playing with the seed pods when I was a child.

Schinus molle another invasive weed we are trying to grow, its pedigree sounds promising, something to try in your arid garden Paul.
K.paniculata is proper hardy I have a smallish tree (10ft) growing in the coldest part of our garden.
I must admit I do not notice it very much till it flowers then it looks a picture but nothing like Stan's K.bipinnata.

Yeah, Koelreutheria paniculata is indeed fully hardy here. I grow the cv 'Coral Sun' and it never had any frozen limbs. At the moment, it is in full autumn glory in shades of orange-red to yellow, with many multicoloured leaves, it looks as if it were in flames!

It's doing its thing for at least a month. Very much recommended for all those, who live in colder climates.

Sorry, for posting so seldomly here, but my new job abroad leaves actually no time for my hobbies anymore.

Hi Stan,

Are you shocked because it was there, or because it was not removed? K. elegans sp. formosana is a serious weed right throughout the Aussie wet subtropics, as I mentioned earlier.

lol,well nothing here that needs to be watered- 99% of whats planted- is never a weed. I thought that whole family was mostly solidly temperate? A all year warm would throw it off? I guess not. It's in that category I suppose with Thuja and Italian cypress..temperate plants grown in all tropical climates. Then you have Mulberry that can grow into southermost Alaska...also grown in Hawaii.
Ben- I thought Brisbane could grow Coconut and Manila palms like south Florida or Hawaii? Not seeing any.

Yes there are many coconut palms in Brisbane, take a look at the coastal areas. Some inland suburbs get surprisingly cold in winter, too cold for cocos anyway.

Here's a few young ones at Gold Coast for instance

Nice link. I've seen them surviving in Perth. Its seems like 80% of Australia's coastal areas can grow them to various degrees.

Here- down the street,Coco's and Howea's. You dont see that often.
