Thuja occidentalis 'Rheingold'

Although the species is a native American coniferous evergreen tree which grows 12-18 m tall, Rheingold is a slow-growing, cone- to dome-shaped, dwarf cultivar that typically matures to only 90-150 cm tall. As the cultivar name suggests, it is noted for its bright golden foliage. Foliage is scale-like and appears in flat, fan-shaped clusters. Foliage turns bronze-yellow in winter.
