Tree ID

This is a pic of an acacia like shrub that I saw growing at Kew lasts summer. It was being used as summer bedding, but I had a plant of it 20 yrs ago, my seed came from Alcatras island, I collected it from some fairly large trees.
It later died from frost but I hadn't seen it since, that is until last year.
I e-mailed Kew to see if they could tell me but all I got was a reply that it might be Caesalpinia, I know its not that.
Any ideas?

 

I can see why Kew thought it may be Caesalpinia, the leaf habit is very similar, I have seen it before but for the life of me cannot remember its name..should I have a brain storm will let you know

 

delonix regia? :rolleyes:

 

Yes it did get stuck to me Nathan, along with a few others of the same type, however the seed didn't seem to stay viable long and I couldn't get any more to germinate.
Something that really stands out is its red stems that zig zag.
Flower buds were just developing on mine when the frost killed it.
Not grown delonix regia dendrobium, but I think that needs to get larger to flower, although its similar leaf.

 

Another pic of the ones at Kew.

 

This is my plant, its two years old at that stage, back in 1987, and just about to get hit by the so called 'October Hurricane'

 

It looks a bit like Albizia Lophantha to me as it is used in summer bedding schemes as it grows fast. Delonix I think not, mine has dropped it's leaves so canot post a pic. Caesalpinia ...possibly, the leaves on my ones are not fully mature but I shall try and get a photo tomorrow, some are already in bud.

 

Have looked at photos again - leaves are like delonix regis - but tree shape's all wrong. :rolleyes:

 

have found a photo at last of A. lophantha - see here http://www.msnucleus.org/watersheds/mission/trees.html#F
It doesn't look the right shape, still, looks longer and thinner in your pics, Pete - but maybe it's a maturity thing. I've seen that all albizias are labelled as invasive, though!! :D

 

Albizzia Lophantha has crossed my mind and been suggested in the passed, but I ordered some seed one year, and nothing grew, but the seed didn't look the same, this was black, not a sign of brown, totally black. Also some of the pics I have googled dont look the same.
So delonix is deciduous, this was evergreen.
Caesalpinia gilliesii I have growing on my house wall, I asume you talking about pulcherrima, do you grow that?
What do you use it for, summer bedding? and in bud already :eek:
I've not been able to get that passed the seedling stage.

 

Thanks for the link dendrobium, I know it looks similar, and to me that pic looks more like julibrissin, especially the flower.
Scroll down a bit to californian buckeye, I've got one of those and its a goodun, but thats another story.

 

Pete
I was refering to Gillesii, I too have never got Pulcherima or Flava past 12 ins high. .the Albizias and Caesalpinias are my own collection I just grow for fun at work. I have one Gillesii in a pot in the garden which has survived the frosts but it is the others that I brought inside in dec (at work) that are now budding up. It is very early and I was surprised to see the buds as normally they flower in july in our glasshouse. They are easy to pollinate and these set seed every year.

Invasive in subtropical and tropical regions, only I wish they were here then they wouldn't such a trial.

 

This one has grown on the wall of my house facing west, its been there for about 15yrs, the flowers dont like rain, but in a sunny year I get quite a good show in August- September.
