These are the plants listed in the most recent Bloom Identification Guide, containing pictures and status of bloom by month. The color in the table below gives the subsection of that guide in which the plant is listed. When two colors are given, the plant has been repeated in both color tables.
This is not by any means a complete plant list for the San Gabriels! It represents only those plants that we record as blooming or not blooming as we hike. See San Dimas Experimental Forest Vascular Plant List by Dick Swinney for a much more complete plant list of one area of the San Gabriels.
