deciduous shrub
Botanical term for a shrub that loses its leaves seasonally.
I planted a deciduous shrub in the garden.
落葉樹 is a deciduous tree, while 落葉低木 specifically refers to a deciduous shrub (low-growing woody plant).
常緑低木 is an evergreen shrub, contrasting with 落葉低木 which loses its leaves.
Compound of 落葉 (leaf fall, deciduous) + 低木 (shrub).
