Carrot Fern

Onychium japonicum (oh-NIK-ee-um juh-PON-ih-kum)

Family: Pteridaceae Non-native

Carrot Fern is a clump-forming, perennial, deciduous fern with wiry black stems holding upright the highly divided lacy fronds that resemble a carrot top and give the plant its common name. It is a native of Asia and thrives in the deep shade of wooded areas. It can reach a height and width of 18 inches, but may take 5 to 10 years to attain these dimensions. Carrot Fern does best in moist, well-drained, organically rich soil in partial shade. It is not particularly hardy and should be sited in a sheltered location. Alternatively, it can be grown in a container and taken indoors during colder winter temperatures. Carrot Fern is a rhizomatous geophyte, meaning that it stores energy in an underground stem (rhizome) and has its growing points underground (geophyte). Maintenance should include removing dead fronds. Diseases, Insect Pests, and Other Plant Problems: No known diseases or insect pests.
