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 - August 17, 2017

Most subalpine meadows are past peak bloom, however that does not mean there are no wildflowers! Many later-season wildflowers like pearly everlasting, rosy spirea, and arrowleaf groundsel are still blooming well. While there are many yellow wildflowers in the park, arrowleaf groundsel (Senecio triangularis) is one of the easiest to identify for its toothed arrow-shaped leaves. It’s also tall for a wildflower, reaching up to 5 feet, and often found growing in large patches along water sources.

Please Note: As snow melts away, it may be tempting to skirt remaining patches of snow that are covering trails. However, by going off trail you are walking on and damaging the wildflowers that you may be coming to see! It is better to stay on trail even if that means crossing snow, particularly in the high-visitation meadows around Paradise and Sunrise.
