Uses by native peoples
(Ethnobotany database)
Juniperus hosts caterpillars of 41 species
of butterflies and moths, in some areas.
Use in a sidewalk strip garden, bloom dates, height, light, moisture, etc. (Pennsylvania). (pages 17 and 41)
Junipers are the ❄ winter host for 🍄︎⚕︎ fungal disease
trellis rust (TR) Gymnosporangium sabinae.
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.)
