Common juniper (Juniperus communis) and single seed juniper (Juniperus squamata) can tolerate partial shade even in cool-summer areas, but should never be planted in dense shade. Single seed juniper grows in USDA zones 4 through 9.

Which Juniper is best for shade?

Ohio State University Extension recommends the blue Pacific juniper (Juniperus conferta "Blue Pacific"), hardy in USDA zones 6 through 9, as the most shade-tolerant variety. This blue-tinged plant develops exceptionally dense foliage, so it can withstand some of the natural thinning that occurs in partial shade.

How much sun does a juniper need?

Junipers grow best in full to partial sun locations with good soil drainage. They need around six hours of direct sunlight each day. Growing them in the shade causes the plants to lose their denseness by spreading out while reaching for the sunlight.
