Poinciana tree, delonix regia from Madagascar and even more spectacular than the jacaranda. It thrives in Queensland but not in Sydney as it is tropical in its requirements. I have seen them flowering in Egypt and often you can see them in the background in the TV series Death in Paradise. These trees flower in December.
Photo of a Jacaranda tree taken a week or so ago at Laidley Qld. Jacarandas flower in Oct/November and mark the start of the exam period at High Schools and Universities.
Pleased to say I have now managed to get one paired with OT. So now have the type in both PT & OT. They are really not easy to find, but wasn't ID'd as one by the seller - a lesser known type perhaps:-
I think it is safe to say I couldn't live with that.
It's like virtually every other rarity when it comes to regular currency coins. Once the variety is documented, a handful appear in reasonably quick time.
