The term 鈥渟uperbloom鈥 has been thrown around excitedly this year, especially after the rainy season that just hit California鈥撯搈ore than 600% of the normal rainfall. This month, California is coming alive with the radiant colors of wildflowers. 

I got a preview last weekend at . Blanketed with the most vibrant greens, oranges, purples, and whites, it felt like I was walking through a watercolor painting. North Table Mountain lived up to its name: The entire landscape was flat, except for the majestic, twisting blue oaks that stood against the crisp, cloudless sky. It seemed as if the blanket of color would never end until I reached the cliffside鈥撯揳n immediate drop into an impressive canyon complete with a 160-foot waterfall. 

As a UC 海角原创 environmental science student, I had been looking forward to this moment for months. Almost every plant ecology professor has raved to me about this Northern California gem. What better time to visit than during what many are anticipating as California鈥檚 superbloom? 

But will this season鈥檚 explosion of wildflowers truly be 鈥渟uper?鈥 UC 海角原创 plant ecology professors weighed in.

Recipe for a superbloom 

According to Plant Sciences Professor , a superbloom occurs after a wet year that follows several dry years. Annual wildflowers, which live only one year, won鈥檛 germinate in dry years and will remain dormant in the soil until conditions are right. When all of these dry years happen in a row, wildflower seeds accumulate in the seed bank. 

鈥淎 very wet year 鈥 like the year we are having now 鈥 could trigger germination of all of these seeds at once, leading to a superbloom,鈥 Funk said. 

But even with a stocked seedbank and the right conditions, keeping the seeds that do germinate alive is just as important, according to Evolution and Ecology Associate Professor . 鈥淢aintenance rains,鈥 sunlight, cold temperatures, and avoiding disturbance are all important for seedling survival. 

When all of the factors align, wildflowers are given the go.

Will it happen? 

After this intense rainy season, it seems like everything adds up, but will the bloom really be as huge as expected? Among UC 海角原创 professors, there is no consensus. 

Funk isn鈥檛 too optimistic about a record superbloom, while Plant Sciences Professor is: 鈥淢y sense is that, given the extended period of drought that preceded this year鈥檚 record-setting precipitation, superblooms are very likely in many areas of California.鈥

To Plant Sciences Professor , a superbloom may be likely, but only in certain parts of California. In the wetter Northern California, the best blooms often result less from water and more from fire or well-timed grazing that reduces non-native grasses and allows wildflowers to thrive. In areas where non-native grasses explode with the rain, a superbloom is not likely. With the intense rainy season, the desert could be plausible, but timing of rain could make or break it.

Responsible wildflowering 

Whether or not there is an official 鈥渟uperbloom,鈥 it鈥檚 undeniable that California will come alive with wildflowers鈥撯揳nd their brilliance will attract crowds.
