Spring in Cairo

I have no idea what most of these flowers are, but I have been enjoying them blooming the past few weeks.  They make grey and dusty Cairo seem much more friendly.  These flowers are inside and just outside of our building:

These are trees blooming around Maadi.  The first tree smells really nice— a good antidote to traffic exhaust fumes!

A close-up of the tree above.  The flowers are bigger than my hands!

These last two are poinsettia bushes(!) and bougainvillea growing up into a tree.
