Cultivars/Varieties
'Aurea' - A slow-growing form (perhaps only 2" per year) that bears golden needles. An irregular plant that may not always have a leader, thus it can form a small tree or a medium-sized shrub.
'Horstmann's Siberlocke' and 'Silver Snow' - Clones with silvery new growth and twisted needles. 'Horstmann's Silberlocke' is widely available and popular. This form features needles that curve upwards to reveal their white undersides. The overall effect is very striking and unusual in texture.
Many dwarf forms such as 'Compact Dwarf' and 'Prostrata' (also called 'Prostrate Beauty') exist with varying shapes and sizes. Some of these may be only rooted cuttings from lower horizontal branches and vertical leaders which arise must be diligently removed. Their form is horizontal-spreading.
