Cultivation Details
Juniperus saltuaria is not a very cold-hardy plant, able to tolerate short-lived temperatures down to around -8°c when fully dormant[1]. Found in the wild mainly in rocky areas, such as at the foot of limestone cliffs and crags and in deep gorges, most abundantly on steep sunny slopes, but also found in deeper mountain soils on less steep slopes. This species is not very drought tolerant and needs abundant seasonal rainfall or snowmelt if it is to thrive[2].
Propagation
The seed requires a period of cold stratification. The seed has a hard seedcoat and can be very slow to germinate, requiring a cold period followed by a warm period and then another cold spell, each of 2 - 3 months duration[3, 4]. Soaking the seed for 3 - 6 seconds in boiling water may speed up the germination process[5]. The seed is best sown as soon as it is ripe in a cold frame. Some might germinate in the following spring, though most will take another year. Another possibility is to harvest the seed 'green' (when the embryo has fully formed but before the seedcoat has hardened). The seedlings can be potted up into individual pots when they are large enough to handle. Grow on in pots until large enough, then plant out in early summer. When stored dry, the seed can remain viable for several years[6]. Cuttings of mature wood, 5 - 10cm with a heel, September/early autumn in a cold frame. Plant out in the following autumn[6, 3]. Layering in September/early autumn. Takes 12 months[3]. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-21. <temperate.theferns.info/plant/Juniperus+saltuaria>
