Juniperus scopulorum Sarg. - Cupressaceae - Rocky Mountain juniper, Rocky-Mountain-Wacholder

Small tree, native to western North America.

„The cultivar 'Skyrocket' is a very popular ornamental plant in gardens, grown for its very slender, strictly erect growth habit. “ http://en.wikipedia.org/wiki/Juniperus_scopulorum

„The neutral leaf oil of Rocky Mountain juniper was analyzed by gas-liquid chromatography. D-sabinene was found to be the major constituent (45.7%) and smaller amounts of D-limonene (11.4%), D-α-pinene (4.2%), γ-terpinene (1.15%), p-cymene (1.4%), L-linalool (1.2%), D-terpinen-4-ol (2.9%), citronellol (0.2%), L-β-elemene (0.2-0.3%), three isomeric cadinenes (2.7%), L-elemol (6.0%), and safrole (1.85%) were isolated. α-Thujene, camphene, car-3-ene, myrcene, α-terpinene, terpinolene, thujone, isothujone, methyl citronellate, sabinyl acetate, sabinol, geraniol, α- and δ-cadinol, and trans-isoeugenol were tentatively identified.“
