A dwarf, evergreen coniferous shrub, slowly growing into a rounded globular shape with a maximum height of 1.5m (5ft) and as much across. Producing dense flat sparays of yellow green foliage. Its strictly conical form is useful as an architectural focal point in a garden, as well as being a good addition to city and courtyard gardens, where ultimate size is an important consideration. Unlike many other golden leaved forms, this cultivar is able to tolerate direct summer sun without its foliage becoming scorched
