Additional notes: Often, consumers will complain of "bugs" on the underside of leatherfern in a floral arrangement. They are referring to naturally occurring spores on the fern. The floral designer may have to educate the consumer on "fern reproduction". Sexual reproduction involves the production of spores on the undersides of fronds. These spores develop into gametophytes, which in turn produce male and female gametes, leading to fertilization and the formation of new sporophytes. Indigenous peoples of the Pacific Northwest historically used Polystichum munitum for various purposes, including as food, medicine, and in ceremonial practices.
