Perhaps it gets its name from its mangle of dark branches or from how its vivid leaves criss-cross each other. Whatever the specific reason, the Japanese Rowan is a stunningly attractive feature. Small in size, its pinnate leaves with lance- shaped leaflets are dark green from spring, but turn a fiery red and gold mixture in autumn. Clusters of white blossoms appear in spring, which give way to small, round orangey-red berries in autumn. The Japanese Rowan thrives in humus-rich, slightly acidic soil in full sun. Low maintenance, only some light pruning is needed. Find Japanese rowan in our Shop! Free shipping from € 50! Plant Environment Usage Known dangers?
