As usual for this time of year my Ivory Curl Flower Tree – Buckinghamia celsissima – puts on the most magnificent display of flowers.
Every year this tree gets bigger and it is pointed out that perhaps it should be pruned but at this time of year there is no way I would consider pruning it.
The masses of cream flowers against the vibrant green leaves – especially when set against the blue sky are just magnificent. So unpruned it shall remain!!
This tree is from the proteaceae family (same as grevilleas and waratahs) and you can see in the close-up of the flower the similarities.
It is a common tree in northern NSW rainforests and is often used as street trees. The street trees are pruned to give a weeping top heavy display which is stunning but I prefer the tree to grow in my garden as it will with not a lot of intervention!

That tree looks like a bee magnet: I was just stung by one two days ago on my finger, and finally the swelling is gone.
Hi Robert
The flowers get bees but not masses of them. it also attracts a lot of other small insects including butterflies and moths. The local lorikeets and small birds that feed on the insects will get in amongst the flowers as well. I must say it is a few years since I had a bee sting and it was never pleasant!
