The large diversity of the flora around Adams is even more apparent in the herbage and, including the tree and shrub species previously mentioned, totals at least 843 species. This is more than any other mountain in the Pacific Northwest. The first extensive list of flora from the area around Mount Adams was published in 1896 by William Suksdorf and Thomas Howell and listed 480 species. Suksdorf had taken it upon himself to catalogue as many species around Adams as he could and the list was the result of his extraordinary collection efforts. This was the most complete list for over a century and has finally been updated by David Beik and Susan McDougall to the current 843 species with hundreds of additional species listed. Adams is home to many rare plants including tall bugbane, Suksdorf's monkeyflower, northern microseris (Microceris borealis), Brewer's potentilla (Potentilla breweri), and mountain blue-eyed grass. The plant diversity is most evident in the many meadows and wetlands on the flanks of Adams. The notable Bird Creek Meadows includes in its famous display, magenta paintbrush, arrowleaf ragwort, penstemons, lupines, monkeyflowers, mountain heathers, and many others. In wetlands, generally at lower elevations, one can find bog blueberry, highbush cranberry, sundew, purple cinquefoil, and flatleaf bladderwort, in addition to many sedges and rushes. Subalpine and alpine meadows and parklands, while not as prolific as the meadows and wetlands of lower elevations, have a display as well with partrigefoot, Cascade rockcress, subalpine buttercup, Sitka valerian, alpine false candytuft, elegant Jacob's ladder, and various buckwheats as prominent players.
