That Sheet of White in the Autumn Wind

On autumn riverbanks, a gust of wind sets white waves rolling—that is the silver reed in bloom. One plant’s spike is like a small broom; ten thousand link into a single sheet, and the river takes on its shivering, rustling look.

The silver reed can stand taller than a person, with erect culms and long, narrow leaves. After flowering, the spikes turn silver-white; they are best in slanting sunlight, when light passes through the fine hairs and the whole flat gleams.

— Tang Dynasty · Bai Juyi, “Song of the Pipa” —

By the Xunyang River at night I see a guest off—

maple leaves and reed plumes shiver in the autumn.

Maple Leaves and Reed Plumes in the Autumn

In “Song of the Pipa,” Bai Juyi wrote of seeing a guest off at night by the Xunyang River—maple leaves and reed plumes shiver in the autumn—making the reed plumes the very sound of parting and autumn waters. Ever since, that line is what many recall first when silver reed is mentioned.

The ancients also used its stems as writing implements, leaving the story of “teaching the child with a reed”: writing characters on the ground with a di stalk, to show that however straitened the household, a child must still be schooled. A grass of the flats—it entered both poetry and family precepts.

How to Tell Silver Reed from Common Reed

By the same riverbank, silver reed is often mistaken for common reed. The rough distinction: silver reed’s culms are finer and more erect, its leaf midribs whitish, its spikes compact and fan-shaped, like brushes in the wind; common reed has stouter culms, a looser panicle, and a spike that spreads into a feathery plume.

Both love the water’s edge and often share the same flats, with similar habits: fond of moisture, tolerant of flooding, rhizomes creeping and networking through the mud—fine material for breaking waves and holding banks.

• How to know it: Perennial emergent aquatic herb; erect culms; long lanceolate leaves; fan-shaped panicles thickly set with white silky hairs.
• Season: Flowering heaviest September–October; spikes turn silver-white October–November, the most striking sight of a riverbank autumn.
• Caution: Pollen is heavy in flowering season; those with allergies should take care on extensive reed flats.

Uses of a Grass

Silver reed’s culms weave into mats and screens, supple and durable; in old times they also served as papermaking material, going to the mill alongside common reed. Cutting di on the flats is a piece of autumn farmwork—bring it home, dry it, and winter has work to do.

In wetland restoration it is a native plant of first choice: the rhizomes anchor the flats’ soil, while stems and spikes leave roosts and cover for birds and beasts. A river needs levees—and its banks need grass.
