Is the guide complete?

The guide is as complete as we can make it right now. We add new flowers constantly after our desert hikes which are almost daily.
But we are probably missing hundreds of less common plants and flowers, but one day we will find them.

When is the flower season?

The season for wildflower annuals reaches its peak from early February to late April. It is followed by a parade of perennials over the summer and fall and into the following year.
Rainfall can be very localized, it needs to fall at just the right time, in the right amount.

Is every wildflower season the same? No. Rainfall and temperatures vary from year to year and from place to place within the desert. Altitude is an important factor, too. Remember that the Anza-Borrego Desert region ranges from well below 1,000 feet to over 5,000 feet. The first flowers appear in the lower elevations and move higher through the spring.

Where can I find more information?
Our Facebook page and website are a good start, if you have any questions let us know.


What will this guide do for you? Our hope is that our guide will help you identify the wildflowers you see, by genera if not by species. It will not make you an expert overnight. Some species, and varieties and subspecies, are difficult to identify, even for an expert.

Never assume you have the right flower, always check if everything adds up, the most common mistake is to ID a flower, just by appearances and ending up with a wrong conclusion.

If in doubt post it on and join our project Flora of Anza-Borrego State Park and adjacent desert.
We try to review every single entry if you provide enough photos.
Or post a request on our Facebook page and we or someone else will be glad to help you out.

*The Anza-Borrego Desert is part of the Colorado Desert, that is a subdivision of the larger Sonoran Desert.

Very good app

Would be awesome if there were a way to tick off flowers we have seen.

Will not download unless WiFi?

Odd. Message says I need to connect to a WiFi network as it’s 150 MB. I tried the WiFi at the new Borrego Springs Library, super slow. Download unresponsive. Went outside to connect to Verizon data at 50x the WiFi speed. Seems to not allow cellular data downloads.

Developer Response ,

A bit strange to give it one star.
I't probably an iOs bug
