Juniperus thurifera (Spanish juniper) is a species of juniper native to the mountains of the western Mediterranean region, from southern France (including Corsica) across eastern and central Spain to Morocco and locally in northern Algeria.[3][4]

The name thurifera comes from the Latin turifer, "producer/bearer of incense".[5]

It is a large shrub or tree reaching 6–20 metres (20–66 feet) tall, with a trunk up to 2 m (6+1⁄2 ft) in diameter and a broadly conical to rounded or irregular crown. The foliage is strongly aromatic with a spicy-resinous scent. The leaves are of two forms: juvenile needle-like leaves 8–10 millimetres (5⁄16–3⁄8 inch) long on seedlings and irregularly on adult plants, and adult-scale leaves 0.6–3 mm long on older plants; they are arranged in decussate opposite pairs. It is dioecious with separate male and female plants. The cones are berry-like, 7–12 mm in diameter, blue-black with a whitish waxy bloom, and contain 1–4 seeds; they are mature in about 18 months. The male cones are 3–4 mm long, and shed their pollen in early spring.[3][4][6][5]

There are two varieties, regarded as distinct by some authors,[3][6] but not by others:[4]

  • Juniperus thurifera var. thurifera. Spain, France. Mature cones 8–12 mm, with 2–4 seeds.
  • Juniperus thurifera var. africana Maire. Morocco, Algeria. Mature cones 7–8 mm, with 1–2 seeds.

Overall, the species is not considered threatened with healthy population in Spain;[1] however, the African population is threatened by severe overgrazing, mainly by goats, and is listed as Endangered.[3][6]

The largest Spanish Juniper forest in Europe is in the Sierra de Solorio.[7]
