"Believe it or not, the Borrego Desert floor went from having very few
blooms on 5 February 2015, to being in full bloom on 20 February 2015, just 15 days later. The number of plants in bloom (counting a max of 99 plants for each species), went from 334 plants of 29 species on 2/5/15 to 3206 plants of 79 species on 2/20/15!
"In fact, the number of plants recorded in bloom on 20 February 2015 is the highest we've ever recorded at this time of year. This is not necessarily a good thing, since it may mean the bloom won't last very long this year, as the plants try to reproduce before they run out of water.
"I've updated the Borrego Desert blooms page with the results of our 2/20/15 trip, including two pictures from the Visitor Center area, and a list of all the species observed in bloom in a walk around the Visitor Center area, and then toward Flatcat and Hellhole Canyon.
