Cryptomeria japonica 'Kilmacurragh' is a flattened-globose, dwarf selection of Japanese cedar with irregular branching and numerous fasciations at the branch ends. Foliage is a combination of adult and juvenile foliage that is colored medium green during the growing season, becoming bronze with the onset of winter. After 10 years of growth, a mature specimen will measure 24 inches (60 cm) tall and wide, an annual growth rate of 2 to 3 inches (5 - 7.5 cm).
This cultivar originated in Kilmacurragh, Rathdrum, Country Wicklow, Ireland. Humphrey Welch first published the name and described the plant in his 1966 book, Dwarf Conifers: A Complete Guide. The nature of this conifer's origin is unfortunately unknown. Many describe this conifer as a dwarf from of C. japonica 'Cristata.'
