GROWING CONDITIONS
Full to part sun, moderate water, hardy to 0°F. In the low desert, it’s probably a good idea to plant in afternoon shade (in summer) while young—when it gets older, it should have no problem with the afternoon sun. Well-drained soil is best. Feed annually with a balanced, organic fertilizer.

NATURAL DISTRIBUTION

TAXONOMY AND NAME
This plant is in the Cupressaceae, the cypress family. There are 75 species of Junipers widely distributed throughout the Northern Hemisphere as far south as tropical Africa, including the Arctic, parts of Asia, and Central America..
In Latin, juniperus is combination of the word junio, which means young, and parere, to produce, hence youth producing, or evergreen, and deppeana is after Ferdinand Deppe, a German naturalist, explorer and painter.

NOTE: there are many other native Juniper species that are sporadically available in the trade. For the region we usually serve, this is the best species.
