Desert Wildflowers

When will they bloom?

When will the wildflowers bloom in the desert?

This is one of the most frequently asked questions about desert wildflowers. Unfortunately, it is also one of the most difficult to answer. Each year, the unique combination of sun, wind, water, temperature and elevation sets the stage for the precise location of the best springtime blooms. Use the following information to make your own predictions for this spring's showing.

Rain is needed in small doses throughout the winter. Too little rain provides a poor climate for seed germination. Too much rain, and the seeds could rot or be washed away. Showers too early or too late in the season may not help the flowers bloom.

Temperature is also critical. Warm days are a good indicator of a full bloom ahead. If the sun gets too hot though, (over 85 degrees F. in February/March) the seeds may become parched and seedlings scorched. Cool nights can assist flower seedlings by slowing the growth of competitors like grasses and mustards. However, very cold temperatures mean bad news for blossoms.

When will the flowers bloom? None of us knows for sure. Each year's bloom is unique in its variety, profusion and timing. From late February through March, you can find blossoms on the desert floor. To plan your visit to coincide with the peak of the bloom, take advantage of the various wildflower hotlines and information sources available from DesertUSA and the state and national parks.

If you should happen to miss the peak, take consolation in the fact that you've missed the peak crowds as well. A tranquil walk through the desert will reward you any time of year. For weekly updates see our Wildflower Watch.

We have a online Wildflower Field Guide that is designed to help you identify desert wildflowers by color, scientific name, region and common name. The pictures are sized to work on the iPod, iPhone and similar devices. With your iPod or phone you will easily be able to identify wildflowers while in the desert. Links for downloads are on the bottom of the Wildflower Field Guide page. A good book is the Mojave Desert Wildflowers Book

Need tips on how to get that great photo, we have several articles on DesertUSA that will help. Links to DesertUSA photography articles.
