Thuja occidentalis 'Mirjam' is a dwarf, globose, golden selection of eastern arborvitae with dense branching and attractive, finely cut golden foliage becomes quite bronze in winter. After 10 years of growth, a mature specimen will measure 16 inches (40 cm) tall and wide, an annual growth rate of 1 to 2 inches.
