Fate of wildflower season depends on winter rain, says expert

A dry fall slowed the growth of Tucson area wildflowers but there is still hope for an above average bloom this winter.

Tucson area wildflowers are among the few flowers that bloom in the winter. However, they depend on seasonal rainfall patterns to blossom.

Despite the December rainfall and the summer monsoon, University of Arizona professor Theresa Crimmins, says that wildflowers will only have an average showing this winter.

“We had decent rainfall in September of last year but then October and November were really dry,” Crimmins said. “So, if seeds would have germinated, they probably didn’t survive too well through that.”

Crimmins says there is still hope for a more abundant season so long as there is enough rain this month and during the coming winter.

“And that really stands out to folks because there’s a lot of color and it’s dense and it’s widely distributed,” Crimmins said. “You’ll just see whole mountainsides covered in these plants.
