Ferns of Berrien County, Michigan

Based on information gathered from the Online Atlas of Michigan Plants, the ferns (Class Filicopsida) of Berrien County number some 25 species representing 2 orders, 7 families, and 14 genera.

To promote the use of native ferns in gardening, I highlight in the list below those species that merited “plant profiles” in Lynn M. Steiner’s book, Landscaping with native plants in Michigan, with the notation NP3 (ferns). Other notations: forests denotes a characteristic habitat where found naturally; while cover (groundcovers), rock (rock gardens), shade (shade gardens), water (water gardens), and yard (front yards) denote recommended suitable uses for natural landscaping.
