Juniper - Needle (Juniperus rigida/communis) - Bonsai Tree Type (Outdoors) Bonsai Care

Evergreen tree originating from mountains of Japan is distinguished by its needle like leaves which grow in groups of three on slender shoots. The bark is brown and flakes away to show orange/red underbark. Often in bonsai this is combined with silver grey driftwood sections. The female tree will bear green berries if grown alongside a male and these turn to purple/black over the next two years.
