Juniperus grandis, with the common names Sierra juniper, Sierra western juniper, and western juniper, is a tree or tall shrub that is endemic to the Western United States.[1][2][3]

Distribution

The tree is native to the Sierra Nevada in eastern California and western Nevada; and the White and Inyo Mountains, San Gabriel and San Bernardino Mountains, and higher elevations of Mojave Desert mountains, in Southern California.[1][3]

It is found in exposed, dry, rocky slopes, flats, pinyon-juniper woodland, and Temperate coniferous forest habitats, including the Sierra Nevada upper montane forest and Sierra Nevada subalpine zone ecoregions. It grows at elevations of 100–3,100 metres (330–10,170 ft).[1]

Description

Juniperus grandis is a medium-sized tree 12–26 metres (39–85 ft) tall. It has a stout trunk up to 3 metres (9.8 ft) diameter, with red-brown bark.[1]

The whorled leaves are scale-like and closely appressed. Most plants are dioecious, but about 5–10% are monoecious.[1]

Its fleshy and berry-like cones are 5–9 mm diameter.[1] Its pollination period is May and June.[3] The seeds are wingless.
