I have a tree growning in our garden and I don"t know what it is. It has leaves that look like a cross between a loquat, a frangipani and a mango. It has huge yellow/orange flowers that initially look like a balloon which eventually open up to look more like a normal flower. I can post a photo, but thought I would post this message now in case it is obvious what the tree is from my description. I live in Adelaide, so the tree is not tropical, (or perhaps it is) Thanks
