This time of year the desert is alive with trees of gold. The Palo Verde trees are all in bloom and we have a lot of them. The flowers are small, about 1/2" in diameter, but can completey cover a tree when in bloom. The rest of the year they are green. Green leaves and green bark. And in real dry conditions they lose their leaves and can photosynthesize through the green bark to stay alive. It's an amazing tree.
