Yellow tree has bouquets for flowers

My neighbor has two of these fantastic trees, one about 15 feet tall and you can tell they like it because there is a younger one about 10 feet tall, which I imagine they planted a few years later. I remembered to bring my camera with me on a walk so I can share with you. I wonder what kind of tree this is; the leaves look rather like feathery ferns. A friend on Facebook answered this question for me, it is a yellow flowered jacaranda.
