Wildflower Viewing in Joshua Tree National Park

Wildflower Viewing in Joshua Tree National Park
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.The extent and timing of spring wildflower blooms in Joshua Tree National Park 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 temperatures to warm a bit before flower stalks will grow. Green-leaf rosettes may cover the ground in January, but flower stalks wait until temperatures rise.
What’s Blooming Now?
Park staff and volunteers compile their wildflower observations weekly during the spring blooming season to produce a list of the wildflowers that are currently in bloom and where you can see them.
