Mount Rainer's renowned wildflowers bloom for a limited amount of time every year. The "peak" bloom for wildflowers is heavily dependent on weather and precipitation patterns, so accurate predictions are difficult. In most years, many flowers will be blooming by mid-July, and by the first of August the meadows should be very impressive. Frost can occur by late August, but even after light frosts the meadows continue to be very beautiful, thanks to changing leaf colors and seed pod development that take the place of colorful blossoms.

For a better idea of what the wildflowers are doing this year, please see the Currently Blooming section below, which summarizes what's blooming where.

Currently Blooming - September 15, 2014

Mountain Bog Gentians are blooming throughout the park. Their deep blue-purple color is a last farewell to summer, as they are one of the final flower species to bloom every year. Another late-bloomer, northern microseris, is bringing bright yellow color to lower elevation areas, particularly around Longmire. Microseris is a popular flower with Pine White Butterflies, which are also starting to appear.
