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.

If you’re a wildflower, how do you attract the attention of pollinators in a subalpine meadow filled with other wildflowers? By being hot pink, of course! Magenta paintbrush (Castilleja parviflora) is easy to spot and recognize – that color is unmistakable. Magenta paintbrush is more common on the eastern side of the mountain, such as around Sunrise, but can be found throughout the park.
The photos featured here are usually taken by park staff and volunteers from all over the park. Share your own wildflower photos in the Mount Rainier Flickr group! Higher resolution versions of wildflower photos are available on Mount Rainier's Flickr page.
