Phacelia viscida var. albiflora
These were common in the areas burned by the recent fires. In 2010 there were a lot of them on upper Jesusita trail, and on the west fork of cold spring (both affected by the Jesusita fire). I’ve even seen a lone plant down by Hendry’s beach. There were fewer in 2011. Also showed up in great numbers after the White Fire (2014, 2015) off Paradise Rd.
The white variety has smaller flowers than the blue (P. v. var. viscida).
