Ferns are the oldest green in the garden, and among the most useful. Where flowering plants sulk in dry shade or thin soil beneath trees, ferns settle in and hold the ground with foliage alone. They ask for little, filtered light, steady moisture, a bit of shelter, and give back texture and calm in the places a garden most often gives up on.

In the landscape ferns are the great problem-solvers of shade. Their fronds range from lacy and fine to broad and almost tropical, and massed together they knit the middle and lower layers of a woodland planting, the part most gardens leave bare. Set against broad leaves or pale bark they read as pure texture, green on green, and bring a cool, unhurried stillness to a shaded bed.

We grow ferns because they do quiet, essential work. In the wild they carpet forest floors, hold moisture and soil against erosion, and shelter the small life of the understory; in the garden they play the same role, covering ground where grass and flowers fail and asking almost nothing in return. Many hold their fronds through mild winters, keeping a shaded bed green when the borders have gone to sticks.

Ferns pair naturally with the broad leaves and quiet flowers of our Herbaceous Perennials, and with the arching lines of Grasses and Bamboos. In a warm, sheltered garden, the bolder textures of our Palms and Sub-Tropicals extend the same layered effect. Give the planting a spring cleanup, cutting the tired old fronds away just as the new ones uncurl, and the bed comes back fuller year after year.
