Juniperus indica is a moderately cold-hardy plant, able to tolerate temperatures down to around -20°c when fully dormant[1]. The climate where it grows is high montane to alpine with a pronounced monsoon phase delivering heavy precipitation (much as snow) from May to October (Spring to early winter)[2]. Requires a sunny position in a well-drained soil. Black Juniper is probably rare in cultivation, often listed as Juniperus wallichiana or Juniperus pseudosabina; the first being a synonym and the latter a closely related species from Central Asia[2]. The recently discovered variety Juniperus indica var. caespitosa is a decumbent form suitable as a ground cover in the rock gardens, but not yet in cultivation. The growth habit of the species is erect, but varies from shrub to small tree. Both forms are commendable for horticulture, but slow growing. In the Himalayas, where Black Juniper is common and widespread[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. The cuttings root easily[7]. Plant out in the following autumn[6, 3]. Layering in September/early autumn. Takes 12 months[3].
