In 1944, with the assistance of Clinton Odell, the Minneapolis Park Board (name at the time) added the large upland section to the Eloise Butler Wildflower Garden. Garden Curator Martha Crone began work immediately in the new addition. Besides doing whatever clearing work was required on the new land, she set out 210 new plants in the area in 1944. These plants were of 30 different kinds that she had collected on four field trips that summer. In 1945 she set out another 4,000, again from field trip collections and from the assistance of others. In some instances she reports that native soil was also brought in for certain plants. She also completed 2,000 feet of new trails that year. For the next several years she set out new marker labels (250 alone in 1946) that were obtained courtesy of Clinton Odell.

In the photo below, taken in May 1948 of the west side of the central hill in the new addition, we see some of Martha's work. Some of the paths shown were removed in later years. We see blooming plants, bags that are either new work to be done or act as protection for plants already set. We also see a number of the marker labels and some evidence of Martha's preferred mass groupings.
