Discover the impressive Zanthoxylum piperitum, also known as the Japanese pepper tree or the Japanese prickly-ash. A unique, aromatic member of the citrus and rue family Rutaceae, this deciduous spiny shrub or small tree hails natively from Japan, Korea, and China. Closely related to the Chinese Sichuan peppers, it offers an essential aromatic and flavor profile to these countries, its leaves and fruits (peppercorns) both being highly treasured ingredients.
This remarkable plant blooms in April to May, producing enticing axillary flower clusters that are yellow-green in color. It's a notable dioecious plant — male flowers can be savored as hana-sanshō, while the female flowers create berries or peppercorns. As autumn arrives, these berries mature into a striking scarlet hue and disperse their black seeds. Adding to its allure, the plant's branch showcases compelling pairs of sharp thorns and highly attractive leaflets framed by eye-catching red husks.
Tolerant of varying conditions, Zanthoxylum piperitum can thrive in anything from deep forest shade to cold temperatures, wind, and drought. This makes it an excellent candidate for almost any garden. Offering more than aesthetic appeal, all parts of the plant are packed with medicinal value. Ground and dry-roasted, its fruit is also a vital component of the traditional Chinese 'five spice' powder. Experience the multifaceted benefits of this intriguing plant in your home or kitchen.
