Observation of Growth and Development and Ornamental Characteristics of 11 Ferns

Ornamental ferns, with their diverse ecosystem types and shade-tolerance, account much in ornamental plants. Eleven ferns, i.e. Adiantum reniforme var. sinen~e, A. capillus-veneris, A. flabellulatum, Nephrolepis cordifolia, Dryopteris fuscipes, Platycerium wallichi, Athyrium yokoscense, Lygodium japonicum, Folium Pyrrosiae, Pteris semipinnata and Aleuritopteris argentea were introduced and cultured in the shelter. Most of them are evergreen and can overwinter and oversummer safely in Wuhan. Adiantum reniforme var. sinense, A. capillus-veneris and A. flabellulatum can germinate throughout the year. Nephrolepis cordifolia, Dryopteris fuscipes, Platycerium wallichii, Athyrium yokoscense, Lygodium japonicum, Pteris semipinnata, Aleuritopteris argentea can germinate in spring and autumn. No sori are found on Lygodium japonicum and Platycerium wallichii.
