Just as the season for annual wildflowers is waning, spring bloom Chapter 2 is in full colorful swing across the desert.

Palo verde trees are beginning their brilliant yellow bloom. Bright fuchsia flowers are showing up on hedgehog cacti. Yuccas are wearing coats of white, creosote bushes are festooned with golden flowers and fairy dusters are showing off in hues of pink and red.

It’s a diverse display of colors and shapes with trees, cacti, bushes and shrubs joining in the April show.

The various plants show their colors a little earlier or a little later at different locations around the Tucson valley depending on altitude, direction of exposure and other factors.

The foothills of the Catalina Mountains north of the city and the Tucson Mountains to the west have colorful plants.

Other sites where this phase of the spring bloom is on display include Saguaro National Park units east and west of Tucson and Sabino Canyon northeast of the city.
