Juniperus komarovii is extremely rare in cultivation, specimens having been traced only at Quarryhill and Howick. In both cases the plants were grown from SICH 716, collected in 1991 at 3360 m near the Liuba river, Sichuan. When seen in 2004 one tree at Quarryhill was 3–4 m tall, forming a multistemmed column with erect branches and spreading to drooping branchlets, but this has since died of Armillaria (H. Higson, pers. comm. 2007). The foliage is a dull sage-green, and as the old foliage is retained and visible the tree has a distinctly dusty look to it. Older trees develop spreading limbs. According to Bill McNamara (pers. comm. 2004), cuttings are difficult to root.
