Joshua Tree National Park - Wildflower Viewing (U.S. National Park Service)

Field Observations as of 3/11/2009
Blooming wildflowers are showing up in more areas of the park as the weather warms. The most noticeable bloom continues to belong to the bladderpod, a large shrub with yellow flowers and dangling, green seed pods. However, Joshua trees, with their showy cream-colored flowers, stand out in Queen Valley and Belle Campground.

Hairy sand verbena, brown-eyed primrose, and several species of forget-me-not are blooming in the Pinto Basin area. Several other species can be found between Cottonwood and the south boundary of the park, including lupines, chia, poppies, and the red-flowered chuparosa shrub.

Shrubs and annuals are beginning to bloom further north now and can be seen along the roadsides from the South Boundary to the North Entrance. For the best viewing , take a walk when small patches of wildflowers begin to show along the roadside. The number of species in bloom may surprise you.

Wildflowers When and Where
The extent and timing of spring wildflower blooms in Joshua Tree National Park may vary from one year to the next. Fall and winter precipitation and spring temperatures are key environmental factors affecting the spring blooming period. Normally desert annuals germinate between September and December. Many need a good soaking rain to get started.

In addition to rains at the right time, plants also require warm-enough temperatures before flower stalks will be produced. Green-leaf rosettes may cover the ground in January; however, flower stalks wait until temperatures rise.

Wildflowers may begin blooming in the lower elevations of the Pinto Basin and along the park’s south boundary in February and at higher elevations in March and April. Desert regions above 5,000 feet may have plants blooming as late as June.
