Changes in plant groupings over 50+ years. In the photo below taken on May 31, 1952 we see an extensive grouping of Foamflower (Tiarella cordifolia L.) along the Woodland path leading to the open bog area. This is near where Garden Guidepost #29 is located today. Large lush ferns mark the right side of the path. In 1946 Garden Curator Martha Crone wanted visitors to have a close-up view of aquatic plants that were in and by the open water pool in the bog, so this path through the center of the bog was added. She was very fond of creating mass groupings of plants as this extensive group of Foamflower shows.
The photo below is two years later on June 3, 1954. The corduroy path construciton is quite clear.
Below -1st photo: The same turn of the path on June 5, 2008. Foamflower still grows here but the specimens are usually found only as single plants. Instead, other native plants are present - Wild Geranium (Geranium maculatum L.) in particular is found here as shown in the photo. 2nd photo: The same part of the path in late April, 2008 showing the topography more clearly.
