Whether it qualifies as a “superbloom” is in the eye of the beholder, but there is no doubt that California’s Carrizo Plain and the neighboring mountain ranges were awash with color as wildflowers put on their annual show in spring 2026.
Landsat satellites began to show the early signs of color in February. By early March, flowers had turned areas around Soda Lake a bright shade of yellow, and by mid-month, they had spread even farther. Yellow wildflower blooms are visible amid the dendritic network of streams flanking the alkaline lake, which dries out completely during drought years. Colors were particularly vibrant across the Carrizo Plain National Monument, even decorating meadows along the zipper-shaped San Andreas Fault with splashes of purple due to blooms of Phacelia ciliata.
Winter 2025-2026 brought bouts of rain and variable conditions that benefited wildflowers. Soaking rains saturated soils in November and December, bringing rainfall totals to nearly twice the usual level, according to a report from the California Department of Water Resources. NASA data cited in the report showed soil moisture remained well above average for the month of February.
The pulse of early rains helped kick-start wildflowers because many seeds need at least a half-inch of rain to wash off their protective coating to germinate, according to the National Park Service. The warm, dry periods that followed also helped. Once established, wildflowers benefit from intermittent rainfall rather than constant soaking.
The Wild Flower Hotline reported that west-facing slopes of the Temblor Range were the first places to come alive with hillside daisies (Monolopia lanceolata) accompanied by California goldfields (Lasthenia californica) and forked fiddlenecks (Amsinckia furcata) in March. The display in the Caliente Range was enhanced by a lack of grass thatch, which was burned off in the Madre fire in July 2025.
Reports from experts on the ground indicate that common goldfield (Lasthenia gracilis), also called the needle goldfield, is responsible for the expanse of yellow near Soda Lake. Individual plants are small, but they often grow in disturbed areas just centimeters apart and bloom simultaneously, creating expansive blankets of color.
In an article for Flora magazine, Bryce King, lead field botanist for the California Native Plant Society, described the Lasthenia blooms there as one …
