Summer winds rushing through Zanthoxylum piperitum - Japanese pepper. This was one of the first plants we planted in Phronesis before we had irrigation in place and fences up and it was the only plants that survived the dry summers and relentless browsing of wild and domestic grazing mammals. in fact the cows and goats would nibble just a little of the the fresh young growth in spring and this resulted in the Japanese Pepper trees ramifying and taking on a dwarf, shrub like form.
These plants are highly valued for their culinary and medicinal properties. The dried, ground pericarp is the famous Sichuan pepper, a key ingredient in Chinese five-spice powder and Japan's shichimi togarashi, prized for its unique numbing quality . Young leaves and flower buds are also edible, used raw in salads or as a flavorful seasoning in soups and with miso paste .
In traditional medicine, it has been used to treat digestive issues and pain .
Ecologically, Z. piperitum shows strong potential in regenerative agriculture. Its leaf essential oils contain bioactive compounds with insecticidal and antibacterial properties, making it a candidate for developing natural pesticides to reduce reliance on harmful chemicals. We have around six plants in various gardens and I have never witnessed any pest damage.
We have these plants available from our nursery this Autumn- https://www.balkep.org/zanthoxylum-piperitum.html
