About this native
Lindera umbellata is a deciduous understory shrub of cool-temperate
Japanese hill forests. The twigs and young bark carry a distinctive,
clean spicy fragrance — long valued for hand-shaved tea picks (kuromoji)
served with traditional sweets, and increasingly for artisanal essential
oil. Pale yellow umbel-like flowers open with the new leaves in early
spring; small black drupes follow on female plants in autumn. Prefers
cool root run, dappled light, and protection from western sun. Marginal
on the Tokyo lowland — site it as understory in a mixed planting rather
than in open ground.
Usage
Mid-layer in a zōki-bayashi (mixed coppice) style garden. Hand-shaved
twigs make traditional kuromoji-yōji (tea picks). Not recommended for
long-term container culture.
