BOTANICAL SAMPLE - NOT GERMINATION TESTED
Life cycle: Perennial
Also called Chinese prickly-ash, this shrub or small tree produces the deliciously spicy/numbing Szechuan peppercorn, indispensable in some Chinese cookery. A few other closely related species also produce Szechuan peppercorns as well. Native to eastern China and Taiwan, this species is hardy to at least Zone 6 and above. It may grow to nearly 25 feet tall, but can also be pruned to remain more manageable. The whole fruit, composed of black seeds inside and rough red-brown shell that naturally splits open, is what is dried and used in Chinese cooking, either whole or powdered (though often it is only the shell that's sold). It can be used as a table seasoning, replacing black pepper, or in the kitchen. Roasting apparently brings out even more flavor. The plant is also considered medicinal, with a resin from the bark and roots being used as a tonic and stimulant.
These seeds were grown in Falmouth, Maine, by our friend Aaron Parker of Edgewood Nursery. He says it took just 5 or 6 years for the tree to reach production.
GROWING NOTES: Seeds should be cold-stratified for 120 days, then soaked in cold water for 24 hours before planting 1/8 inch deep. Happiest in zones 6-9, it will thrive in loamy soils that are well-drained but also retain moisture. It can handle full sun of partial shade.
