There’s something particularly breathtaking about wildflowers in the Sonoran desert. Maybe because of the way they transform the landscape. Maybe because their season is so brief and precious. Maybe because some years Mexican poppies turn entire hillsides gold, and other years there is only a sprinkling of color. The best years become part of local lore.

People try to guess when we’ll have a good year for wildflowers, but they’re hard to predict, like the weather. Actually, it’s the weather for months before wildflower season that has the largest impact on what you’ll see in March.

Because of their unpredictability, knowing if/when/where wildflowers have arrived depends on someone spotting them and spreading the word – which is much quicker with the internet amplifying the message.

Where to find Arizona’s spring wildflower sightings online

DesertUSA covers regions throughout the Southwest and as far north as Oregon. People submit notes (and sometimes photos) about where they’ve spotted wildflowers. There are also reports from Arizona State Parks, Boyce Thompson Arboretum, and Grand Canyon National Park.
The Desert Botanical Garden has a Pinterest map of Arizona wildflower sightings. The DBG itself is a great place to see wildflowers.
During the season, Wild in Arizona has more detailed field reports from two nature photographers.

Even though it’s early, Phillip and I have already been spotting wildflowers. There were a few as we headed north from town on the 17 over the weekend. A week before that we spotted a single yellow flower while hiking at South Mountain. It might’ve been the first Mexican poppy of the season or an earlier-blooming desert sunflower.

Either way, it looks like it could be a good wildflower year.
