Wildflower Report 2017

About This Blog

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. Park staff and volunteers compile their wildflower observations weekly during the spring season to produce a list of the wildflowers that are currently in bloom and where you can see them.
