Phyllitis scolopendrium (syn. Scolopendrium vulgare) (hart’s-tongue fern), readily distinguishable from any other species by its, strap-shaped leaves, which vary in length from 1 to 1-½ ft., and contrast beautifully with the feathery appearance of other ferns. One of the few adaptable ferns, finding a home on walls, by the waterside or in the border (either in full sun or part shade). Can also be grown as a pot plant in the house. There are many varieties, of which P.s. Crispum is the most commonly grown.
P.s. Crispum, 1-½ ft., paler green, more delicate in texture, and beautifully crimped along the leaf margins. There are also forms with baby plantlets on the fronds. These are easily separated and can, with care, be grown on to adult stage.
