    "The wilderness and the solitary place shall be glad…and the desert shall rejoice, and blossom as the rose. It shall blossom abundantly...." -Isaiah 35:1-2

    Springtime is the best time to explore and learn about the beauty of the desert southwest. Spring comes early to the desert and brings all of the dry, dead-looking plants vibrantly back to life. An astonishing variety of wildflowers, nurtured by winter rains, can bloom in wondrous profusion and carpet the desert floor and mountainside slopes with glorious color. Some places burst forth in a rainbow of colors, while other areas become carpets of solid gold or purple. Every year, thousands of visitors time their travels through the American Southwest to coincide with the desert wildflower season. This year we have already witnessed a spectacular display.

    Anyone who thinks that the desert is a barren wasteland of cactus and rocks should see the amazing array of greenery and color it has now! Property owners and builders, who usually thoughtlessly scrape away the desert topsoil to create their own landscapes, should take a walk through the virgin desert in springtime to behold all of the tiny miracles of nature that normally remain hidden to the developer's eye. The Sonoran desert has more different plant varieties than any other desert on earth, a fact that is especially noticeable at this time of year. Once you see the desert in all of its springtime finery, you will surely appreciate it a lot more.

    The varieties and duration of wildflower blooms depend on a mysterious code of rainfall, temperature, and sunlight that is unique each year. A good wildflower season is determined by the spacing of rains in the fall and winter. The rains must begin in the autumn and continue through January and February, with at least an inch each month. Desert areas that receive the most rain during this time will usually have the most color. Numerous other factors besides rain can affect the wildflower bloom. Unseasonably cold weather inhibits seed germination. Unseasonably warm weather at the time seedlings emerge can cause wilting. Excessive winds can prematurely dry out tender wildflowers. But even in the "worst" years, you will be able to find wildflowers in certain places.

    Desert wildflowers can be a quick show, so enjoy them while you can. They can germinate, bloom, scatter seeds, and die within a matter of weeks. The peak wildflower season in Arizona's lower deserts is usually in March and lasts for about two weeks, but this year they began blooming earlier. As a general rule, the flowering season starts at the bottom in the lower desert elevations and works its way up to the higher altitudes. The wildflower season may begin as early as January at the lowest elevations and last into April and May at higher elevations.

    Wildflowers may be found throughout the southwestern deserts, depending on the soil type and surrounding vegetation, which are also important factors. The best locations for wildflower growth seem to be on well-drained, south-facing slopes. Some popular viewing areas in Arizona include: Picacho Peak, the Apache Trail, Tonto National Monument, Interstate 10 west toward Tonopah, the Pinal Pioneer Parkway between Florence Junction and Tucson, the Hassayampa River Preserve, the Phoenix Mountain Preserve, Estrella Mountain Regional Park, Pinnacle Peak, South Mountain Park, and the Desert Foothills area north of Phoenix.

    Gold poppies and purple lupines generally dominate the spring wildflower show, but also look for yellow desert marigolds, white blackfoot daisies, red-violet owlclover, orange globe mallows, red penstemon, yellow brittlebush, pale purple brodiaea, pink filaree, and many more.

    Did You Know…?

    Because of the geographical position and range of altitudes in Arizona, practically every kind of wild flowering plant native to North America can be found somewhere in this state. In fact, almost 40% of the more than 2,000 flowering plants in the world are found in Arizona. The upper Sonoran desert is home to as many as 400 different species of plants.

    When is a Wild Flower Not a Wildflower?

    The term "wildflower" (one word) refers specifically to annuals and herbaceous perennials that appear above ground only in wetter than average years. Examples of these are desert lupines and gold poppies. The term "wild flower" (two words) encompasses all of the wild flowering plants, including perennials such as brittlebushes, cacti, and ocotillos. Many perennial desert flowers bloom every year, even in poor years for wildflowers.

    Grow Your Own Wildflowers

    Growing wildflowers in home landscapes is a popular pastime. If you plant your own, you will always have a wonderful show since you control how much water they get. For a traditional spring showing, you will have to plant your wildflower mix in October. But you can have a second wildflower season by planting a different kind of mix at the end of spring for a late summer show. These will be wildflowers that like hot temperatures combined with wet weather (monsoon season), rather than cool temperatures and wet weather.

    Some seed companies sell southwestern wildflower mixes and/or individual seeds in packets and/or bulk quantities. Wild Seed Inc. located in Tempe, Arizona has mixtures in any amounts for yards or large-scale revegetation. (Call 602-276-3536.) A local supplier, Homan Brothers Seed, has a 4000 square foot seed processing and storage center located at 1540 W. Happy Valley Road in Phoenix, Arizona. (Phone 623-869-8457 or email You can also check with local nurseries and at the following websites:,,, or go to the Arizona Native Plant Society website at for a complete listing of Arizona native plant and seed sources.

    Take An Armchair Tour of the Desert in Bloom

    Wildflower enthusiasts considered the spring of 1995 to be the best year in more than a decade. Nourished by just the right amount of winter rain and coaxed into bloom by the warmth of the sun, for a few brief weeks the Sonoran Desert was a breathtaking bouquet of vivid color. Channel 8 camera crews explored Arizona by automobile, on horseback, and on foot to capture this extraordinary visual event so viewers could enjoy an "armchair tour" of desert wildflowers at the peak of their bloom. The locations where they gathered their colorful images include: Desert Botanical Garden, Boyce Thompson Southwest Arboretum, South Mountain Park, Superstition Mountains, Saguaro National Monument, Organ Pipe National Monument, Tonto National Monument, Picacho Peak State Park, Beeline Highway, Apache Trail, Carefree Highway, and Wickenburg. For more detailed descriptions as to where they found the flowers, go to: "Desert Wildflowers" is a glorious celebration of spring that showcases the extraor dinary diversity of Arizona's natural landscape. "Desert Wildflowers," A KAET production, can also be purchased on video for $19.95 at the KAET Store of Knowledge (Scottsdale Fashion Square), Arizona Highways (1-800-543-5432), and the Desert Botanical Garden (480-941-1225).
