This slow-growing cultivar is broadly upright or oval in form, with dark green, small needles and a compact growth habit. 'Jervis' is a natural form that was found in the wild and vegetatively propagated for the nursery trade. It's ideal in rock gardens or as an accent among lower growing perennials or seasonal displays. This plant prefers acidic soils that are well-drained yet consistently moist and bright light to full sunt.
