Superbloom

Because some invasive grasses, such as bromes, will compete with native flowers for moisture, the desert must remain dry enough prior to the bloom to keep them from becoming established.

[1] The desert must receive rainfall in the autumn, and this rain must penetrate deep into the soil matrix in order to reach a majority of the dormant seeds of flowering plants.

If subsequent rainfall is excessive or inundating, the young plants may be carried away in flash floods; if it is inadequate, the seeds will die from dehydration.

Anza-Borrego Park and Carrizo Plain National Monument are some of the most popular places to witness a superbloom, and the bloom of 2019 was particularly abundant.

Dominant color patches of hills are bright yellow (Monolopia lanceolata, Caulanthus inflatus), purple (Phacelia tanacetifolia), magenta/dark pink (Castilleja exserta), and orange (Eschscholzia californica, Mentzelia pectinata).
