A large group of related plants in cypress / juniper / redwood  family Cupressaceae (in 🌲︎ conifer  order Pinales ), including species common juniper  Juniperus communis, creeping juniper  Juniperus horizontalis and ◼︎ eastern red cedar  Juniperus virginiana.   Please let us know which other species you would like to see here, using the button at the bottom of this page.

Different species are native 🌍︎🌎︎🌏︎ worldwide, mostly in the Northern Hemisphere.   🗺 Map by county (🇺🇸 USA-48) (color key).

Junipers are the winter host for 🍄︎⚕︎ fungal disease trellis rust (TR)  Gymnosporangium sabinae.  Adobe Acrobat Reader file

Which then transfers to nearby 🍐︎ pear  genus Pyrus as the ☀︎ summer host.  Then back again!

So in areas that may have this disease, do not plant these two hosts within 300 m (1000 ft) of each other!  (In most towns, 3 blocks, maybe.)

Uses by native peoples
(Ethnobotany database)

Juniperus hosts caterpillars of 41 species
of butterflies and moths, in some areas.

Male trees score 🤧︎ most allergenic (10 out of 10) on the OPALS™ Ogren Plant Allergy Scale.

🌲︎ Conifer  order Pinales have 'naked' seeds — thus called gymnosperm — by:

  • not enclosing its seeds with any ovary structure, and
  • packaging their seeds in cones (a different type of female repro­ductive structure, apparently).

However, although juniper  genus Juniperus and yew  family Taxaceae are grouped with the 🌲︎ conifers above, these two subgroups violate both these rules, with seed cones that are fleshy and berry-like.
