Ruella Simplex (brittoniana), wild petunia

The ID is wrong. Please visit the new link Tabebuia Rosea.

I found this growing in Quezon Memorial Circle, and the other even nearer, in Philcoa! Googling for best matching image result in Mexican Petunia dwarf ruella brittonia katie, but this one is a small tree, higher than 6 feet, not a ground cover!

This plant have become an invasive species in Florida.
