Plants of Marys Peak

Marys Peak is a lodestone for botanists and recreationists because of its distinctive vegetation and diverse plant life. A number of plants on the summit are at the extremes of their range. Botanists have recorded more than 200 flowering plants in the summit area. As you hike up the peak or walk about the summit area you will encounter three main plant habitats - forest, dominated by either the majestic noble fir or Douglas-fir, the summit meadow, and a south western-facing fragile ’rock garden”.

Below are listed 60 of the common flowering plants together with their growth form (whether they occupy the Tree layer, Shrub layer or Herb layer), and principal habitat.
