Paper bush, Edgeworthia chrysantha, spends the growing season as a quiet, blue-green shrub and saves the show for the dead of winter. In late winter and earliest spring, while the branches are still bare, the shrub hangs rounded, downward-facing clusters of small tubular flowers from the tips of every stem, silvery-furred buds opening to warm yellow throats that carry a sweet, daphne-like fragrance across cold air. A cousin of Daphne and the native leatherwood Dirca in the family Thymelaeaceae, paper bush shares the tribe's supple, hard-to-snap branches and honeyed scent.

The common name is earned. In Japan, where the shrub has been grown for centuries under the name mitsumata, the long, fine fibers of the inner bark are one of the three traditional sources of washi paper, alongside kozo and gampi, and were long used for the country's banknotes, prized as among the hardest currency in the world to counterfeit. In Chinese folk medicine the plant has a second life: the flowers, bark, and roots have been used for their anti-inflammatory and pain-easing properties, and the flower buds in particular served as a traditional remedy for ailments of the eyes.

In the garden paper bush earns a spot near a door or path where the winter fragrance and the odd, architectural branching can be met up close. The plant builds a rounded, softly tropical-looking mound five to six feet tall and about as wide, with bold blue-green leaves through summer and a distinctive forking, three-into-three branch pattern that shows beautifully once the leaves drop. Give the shrub rich, moist, well-drained woodland soil and dappled shade, and pair the plant with hellebores, snowdrops, and early species crocus for a winter picture that smells as good as it looks.

Paper bush asks for little beyond shelter and a kind soil. Hardy in USDA zones 7 through 9, the shrub prefers protection from harsh afternoon sun and drying wind, resents soggy ground, and rewards a yearly mulch with steady health and heavier bloom. Slow to make a large plant but worth every season of waiting, Edgeworthia chrysantha is one of the great winter luxuries of the mild-climate garden.

Design Notes

Winter luxury for shade. Paper bush belongs where the cold-season fragrance and the sculptural, forking branches can be met at close range: beside a door, along a well-used path, or at the front of a woodland border. The plant forms a rounded, tropical-looking mound five to six feet tall and wide, so give it room. Underplant with hellebores, snowdrops, and early crocus, set the shrub against evergreens that show off the pale winter flowers, and keep the plant out of harsh afternoon sun and drying wind.

Flower, Fruit & Foliage

Rounded, nodding clusters of small tubular flowers, silvery outside and yellow within, sweetly fragrant on bare stems in late winter to early spring

Flower. Dense, downward-facing pompons of small tubular flowers, silvery-furred in bud and opening to warm yellow throats, carried at the branch tips through late winter and early spring before the leaves.

Fragrance. Strong and sweet, daphne-like, carrying well on cold, still air, which is much of the reason to grow the shrub near a path or door.

Foliage. Bold, blue-green, lance-shaped leaves through the growing season on a rounded shrub with a distinctive forking, three-way branch pattern, bare and sculptural in winter.

Care

Light. Dappled to part shade; shelter from harsh afternoon sun.

Soil. Rich, moist, well-drained woodland soil with plenty of humus; the shrub resents both drought and soggy ground.

Water. Keep evenly moist, especially through summer; mulch to hold moisture.

Pruning. Little needed; remove wayward or damaged stems just after the winter flowers fade.

Hardiness. USDA zones 7 to 9; shelter from drying wind improves both survival and bloom.

History & tradition

Paper bush leads a double life in the native range. Beyond the papermaking that gives the shrub its name, the flowers, bark, and roots have a place in Chinese folk medicine, valued traditionally for anti-inflammatory and pain-easing effects, while the dried flower buds were used as a remedy for ailments of the eyes.

Modern pharmacological study of the species is still sparse, so these notes describe traditional use and early phytochemistry only. This is not medical advice; members of the family Thymelaeaceae contain irritant compounds, and no part of the plant should be used medicinally without expert guidance.
