Flowering trees

First to bloom, the huisache.

 Then the retama.

 

(The retama is a relative of the desert palo verde tree.  It has chlorophyll in its trunk and branches so it can carry on photosynthesis even when it has dropped its leaves to conserve moisture during dry spells.)

 

And now the mesquite.

 

What is it with Texas trees all blooming yellow flowers?

 

Oh yeah, and the prickly pear.
