Hart's Tongue Fern

Asplenium scolopendrium

Low forming clump of wide, upright, leathery green fronds.

Hart's-tongue Fern has an unusual, almost tropical appearance, with wide leathery green fronds that are strap-shaped. Plants form a low clump, best suited to the rock garden or for edging in a moist woodland garden. Excellent drainage is required, and a limestone-based soil is best, rather than acidic. Mulch around the plants with compost to keep soil moisture even. Evergreen.
