Small, somewhat airy fern that is excellent for shaded rock gardens. Emerges in very early spring. Strong grower, producing new fronds all season long. Easy to grow if its cultural needs are met. Fronds may turn brown in midsummer, but new fronds are produced. Fronds have brittle central stems and break easily, hence the common name. Needs a sheltered location protected from prevailing winds. Native to deciduous woods, edges of wooded bluffs, shaded banks of rivers, wooded areas along rocky streams, upper slopes of ravines, and shaded areas along cliffs.
