The massive jacaranda mimosifolia (native to Brazil) which is dominating my front garden, laughs at your suggestion that it does not leave much mess on the ground.

It regularly carpets the area below it in purple flowers, tens of thousands of small leaves, hundreds of twigs/seed pods and a few larger dried branches. Not just one season either - it flowers multiple times a year with how weird the weather is nowadays. The birds and bees like it though so we’re cool.
