Sounds like a lovely tree.* Got any pictures?
Pink Shaving Brush Tree aka Pseudobombax ellipticum
*aka Pseudobombax grandiflorum comes to mind but it's not native to the araa.
I thought of another tree, but it gets large thorny spines on the trunk and is a rare tree in Pakistan.
When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
