Two years after steady rains followed by warm temperatures caused seeds dormant for decades under the desert floor to burst open and produce a spectacular display dubbed the "super bloom," another winter soaking this year is expected to create possibly an even better show by Mother Nature.

Having two super blooms in two years is highly unusual. In California, super blooms happen about once in a decade in a given area, and they have been occurring less frequently with the drought.

The 2017 super bloom was the best seen in the Anza-Borrego Desert State Park in 20 years and drew mass crowds to Borrego Springs, a town of 3,500 that abuts the park.

"There's just an abundance in where it's blooming and it's coming in waves," said Betsy Knaak, executive director of the Anza-Borrego Desert Natural History Association, which tracks the blooms.
