Tanner’s sumac (Sicilian sumac)

Rhus coriaria

Mediterranean shrub with pinnate leaves and dense panicles of small dull-red fruits, dried and ground to produce the lemon-tart sumac spice of Levantine cuisine. Leaves are the source of one of the highest tannin contents of any plant.

Growing notes

  • Tannin and brown-to-black dye extracted from leaves and twigs by boiling — historically the principal European source of vegetable tannins for leather processing and the highest-quality leather (Morocco leather)
  • Distinct from staghorn sumac Rhus typhina (already in the database from batch 6) — R. coriaria is the spice and leather sumac of the Mediterranean, not the autumn-colour ornamental of North America
  • Dried ground fruits are the sumac spice of Levantine and Persian cooking — sharp, tart, lemon-flavoured
  • WARNING: A few related species in the Rhus genus (notably poison sumac, Toxicodendron vernix) are dangerously toxic — identification certainty is essential before harvesting wild material
