Visitors to the park this summer are extremely interested in the planting activity on the Rim from the entrance of the Rim Road to the Lodge. The rim walk winds through this planted area among native shrubs and flowers.

As the soil on the Rim is pumice and not favorable to plants, rich soil has been transplanted from bogs and stream banks and spread over the pumice.

At the head of the Lake Trail is an excellent planting layout of mountain ash, black twinberry, red twinberry, pink spirea, and native grass which forms an intersection of the lake and rim walks.. In the shaded locations under the mountain hemlocks are planted western bleeding hearts, alpine phlox and mountain valerian, The false green hellebore, Coville's aster, fireweed and Crater Lake currant are all prominent at this season on the Rim edge. The Crater Lake currant is being used as a creeping plant to beautify the new Sinnott Memorial Building. In between the rocks of the building are planted a matted beard tongue, the lace fern, seedum, softening the lines of the architecture. These plants have been obtained from the rock crevices on the side of Garfield Peak.
