Asplenium Anitiquum osaka. The Japanese birds nest. A very lovely form of fern with soft green ruffled fronds. Asplenium ferns are epiphytic which means they love to grow on other plants and can be found naturally growing high in the trees of the rainforest. Water really well in summer but keep drier in winter. An excellent evergreen ornamental indoor house plant great for air purifying. Shaded position or filtered light. 0.5m to 1m
