Sansho likes half day to full sun, well-drained soil and is pest and disease resistant. It is hardy to minus 15 degrees F., USDA Zone 5.

Latin Name: Zanthoxylum piperitum
Site and Soil: Sansho Pepper likes 1/2 day to full sun and well-drained soil.
Rootstock Description: Self-rooted
Pollination Requirements: Sansho appears to be self-fertile and bears monoecious flowers though many sources state they are dioecious. It’s often been thought that pairing Sansho with Sechuan for pollination would help as they are closely enough related to pollinate each other but it now appears that they will fruit with or without the presence of the Sechuan pepper or other Sansho peppers.
Hardiness: Minus 15º F
Size at Maturity: 12-15 ft. in height.
Pests & Diseases: Sansho is not bothered by pests or diseases.
USDA Zone: 6-9
