Most of the photos here were taken at various points in or near Tucson Mountain Park over several days. Most folks I've spoken to say they have never seen the Palo Verde's bloom this spectacular and in the ten years i have lived in Tucson I have never seen a bloom this massive.
As we approach May the bloom will fade and be replaced with the Saguaro blossom which will once again bring me into the desert to try my hand at getting the quintessential Saguaro blossom for my database.
Taken from Gates Pass.
The above photo was taken just outside TMP in Saguaro National Park where the bloom had already reached it's peak.
On the way home I couldn't resist stopping and waiting to see the sunset in the park. Turned out to be worth the wait.
