One of my favorite trees is Couroupita guianensis, known by a few other names (ayahuma, cannonball tree). When mature the trunks grow some beautiful flowers that can cover the trunk (wiki link has a few good pics). Native to South America, it's a revered tree in Amazonian plant shamanism (all parts of the plant can be used medicinally; spiritually it is one of the big ones, an entire school of its own). It made its way to India in the 1800s where it holds a lot of renown and importance now.

Superb flowers but very dangerous to stay under the cannonball tree.
