Utsu Semi Japanese Maple is a small, slow-growing deciduous tree with an upright habit and strongly textured palmated foliage that emerges vibrant light before turning scarlet to orange in fall. Small, non-showy but attractive umbels of red flowers bloom in spring followed by samaras. Grows best in rich, moist, slightly acidic well-drained soils. Prefers full sun in cooler climates, but needs afternoon shade in southern areas.
