Wildflower season usually begins with the large, cream-colored blooms of the Joshua trees in late February, followed by colorful annuals at the lower elevations around the south boundary of the park. Sometime in March, the bloom will follow rising temperatures into the higher elevations of the park. Cacti usually wait until April or May to produce their bright, waxy flowers. Along the north side of the park, desert dandelions carpet the ground from 29 Plams to Joshua Tree. Joshua trees and Mojave yuccas have been blooming for several weeks in Queen Valley, Lost Horse Valley, and up in Black Rock Campground. Cacti are also beginning to bloom throughout the park.
