Two Leaf Lion Tongue Fern. This rare cultivar of the Asian Tongue Fern has a multi-branched leaf which flares out somewhat like an elk's antler. These ferns are amazingly cold hardy, doing well from zones 7b to 10. If grown in a container, they do best in a loose and open soil mix similar to an orchid mix. Their roots are quite shallow, which if kept in a high enough humidity, they can be grown on a bark slab. In the wild this genus is epiphytic, growing on tree trunks or over rocks. If grown in a wire basket, it will shortly look like a small staghorn fern which can be left outdoors for much of the winter (see the picture below). Give them shade with uniform moisture if grown in the landscape. Quite impressive!
