Tongue fern from Asia is also known as a leather fern in reference to the robust thickness and texture of the leaves. These evergreen ferns creep stoloniferously to create patches. Not rocket fast, but you can enhance growth in rich, well drained soil with regular SUMMER water. This semi-subtropical-ish fern grows fastest during summer so thats when you supply water. Otherwise it is tolerant of very dry conditions and will make due with one spring moisture burst of growth. Very good appearance year round. Part shade to shade- reasonable shade, not a dark planter under the Brady Bunch stairway but bright shade. Mixes well with Aspidistra elatior (Cast Iron Plant) and Asarum splendens a green and textural combination that looks good year round. And sometimes in dry shade thats the best you can ask. HEH. To 18″ tall and spreading several feet wide with care. Long lived and cold hardy to about 5ºF. Avoid strong subfreezing east wind which can scorch the edges. Great in shady containers. Even successful as a houseplant. Moderate deer resistance.
