About Japanese pepper plants

The Japanese pepper tree has been grown for centuries in Japan, where both the leaves and peppercorns are used in traditional cooking. The leaves are used fresh for their bright, citrus-like aroma, and the peppercorns ripen to release a tingling, numbing spice that enhances grilled meats, noodle dishes, and pickles.

As a hardy shrub or small tree, the Japanese pepper plant adapts well to UK conditions, making it a great choice for gardeners who want to grow something a little different. With delicate foliage and clusters of vibrant peppercorns, it looks striking in borders, pots, or as part of a kitchen garden.

All of our pepper trees are carefully raised to thrive in your garden, giving you the chance to enjoy a piece of Japanese culinary culture at home. Shop now, or take a look at our wider pantry collection for more Japanese ingredients to cook with.

Frequently asked questions

The pepper tree is valued in Japanese cuisine for its leaves, which are used fresh in spring, and its peppercorns, which are harvested later. The leaves add a fresh, citrusy note to soups and rice dishes, while the peppercorns provide a spicy, tingling flavour that pairs beautifully with grilled meats, noodles, and pickles.

Yes. Pepper trees are hardy plants that can grow well in the UK climate. They prefer a sunny or lightly shaded position and well-drained soil. They can be grown in pots or directly in the ground and respond well to pruning, making them suitable for a range of garden sizes.

They are closely related but not identical. The Japanese pepper tree (Zanthoxylum piperitum) is native to Japan and produces Sansho peppercorns, which have a brighter, more citrusy flavour compared to Szechuan (Zanthoxylum giraldii) pepper. Szechuan is typically considered the Chinese version of the Japanese sansho tree. Both belong to the same genus (Zanthoxylum) and share the characteristic tingling, numbing spice.

In ideal conditions, a Japanese pepper plant can reach 2 metres in height, though it can be kept smaller with regular pruning. Its compact size and attractive foliage make it a popular choice for gardens, patios, and kitchen planters.
