Tasmanian Tree Fern
Oh how we wish this magnificent tree fern was just slightly more cold hardy! A truly extravagant creature from down under the Tasmanian Tree Fern eventually forms trunk that can grow over 10 feet tall! It’s so beloved that gardeners in the Northwest have tried for years to grow it with all sorts of overwintering techniques, sometimes with great success. But to be sure it overwinters it can be grown in a pot and grown indoors, though it is thought to be the most cold hardy of any tree fern. Does amazingly well along the California Coast and can make a gorgeous house plant! Prefers shade and ample moisture.
