Zanthoxylum Piperitum
Japanese Pepper Tree, Japanese Prickly Ash
Japanese Prickly Ash becomes a dense shrub or small tree with glossy, dark green foliage. Each compound leaf is divided into many smaller leaflets, giving the plant a lighter texture than its sturdy branches suggest.
Paired thorns occur along the stems. Small yellow-green flower clusters are followed by reddish fruits containing dark seeds. Position the plant where its branching and fruit can be enjoyed without the thorny stems obstructing a walkway.
Choose a sunny site and allow room for the broad mature framework. It is best treated as a substantial landscape specimen rather than a small border filler.
