Morristown National Historical Park contains many different plant communities including mature and successional forests, open fields, cultivated sites and wetland vegetation. In 1995 an herbaceous inventory identified 291 species of herbaceous plants as well as 22 species of ferns.
Flowering Dogwood is the most common understory species. Invasive nonnative plants have begun to dominate the forest understory in all of the parks units. Prevalent invasives include Siebold's Viburnum, Japanese Wiregrass, Japanese Barberry and Oriental Bittersweet.
Fifteen fields totaling 122 acres are maintained within the park. These fields originally were used for agricultural purposes but now serve to retain a historic appearance. Field vegetation includes grasses and herbaceous and woody plants that attract numerous species of birds, insects, and other animals.
