Juniperus sabina
Safety & Hazards
The whole plant is poisonous and can produce abortions[1]. The foliage and the seeds contain sabinol (a terpenic alcohol) and gallic acid, which is transformed into pyrogallol. Consumption of the foliage causes a severe irritation of all mucous membranes. The sabinol attacks the nervous system, causing convulsions. The pyrogallol blocks the intestinal circuit completely. Death occurs quickly[2].
Cultivation Details
Juniperus sabina is a very cold-hardy plant, able to tolerate temperatures down to around -35°c when fully dormant[2]. This species is most abundant on sunny, dry slopes in mountains with a mesic climate like the Alps; its drought tolerance accounts for its wider distribution in Asia into the Artemisia steppe and desert zones[3] Succeeds in most soils if they are well drained, preferring a neutral or slightly alkaline soil[4, 5]. Prefers a limestone soil[4]. Succeeds in poor soils and in light shade[6]. Established plants are drought tolerant, succeeding in hot dry positions[7]. Tolerates maritime exposure[7]. A very ornamental plant[4], there are many named varieties[8]. All parts of the plant have a powerful pungent smell[9]. Plants can be dioecious or monoecious. Male and female plants must usually be grown if fruit and seed are required. The plant is sometimes attacked by a rust, this is a fungus with an aecidial stage on the leaves of pear trees[4]. Plants are resistant to honey fungus[10].
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[11, 12]. 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[4]. Cuttings of mature wood, 5 - 10cm with a heel, September/early autumn in a cold frame. Plant out in the following autumn[4, 11]. Layering in September/early autumn. Takes 12 months[11]. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-21. <temperate.theferns.info/plant/Juniperus+sabina>
