Lindera obtusiloba, the blunt-lobed spice bush,[1] is a species of flowering plant in the laurel family Lauraceae, native to China, Korea and Japan. It is a spreading deciduous shrub or small tree growing to 6 m (20 ft) tall and wide, with glossy aromatic leaves and deep yellow flowers which appear in spring before the leaves.[1] Juvenile leaves are lobed (as the name suggests) and are deep purple. The leaves often turn yellow in autumn.
