Source-derived summary

Rhus coriaria, commonly called Sicilian sumac, tanner's sumach, or elm-leaved sumach, is a deciduous shrub to small tree in the cashew family Anacardiaceae. It is native to southern Europe and western Asia. The dried fruits are used as a spice, particularly in combination with other spices in the mixture called za'atar.

Etymology

The word originally comes from Hebrew סמק, then through the Aramaic summāqā 'red', via Arabic, Latin, and French.

Distribution and habitat

Rhus coriaria is native to southern Europe and western Asia, including the Eastern Mediterranean, Crimea, Caucasus and northern Iran, but is now naturalized in most of the Mediterranean Basin as well as Macaronesia.

Cultivation

Rhus coriaria is a hardy, drought-tolerant, deciduous shrub growing to 3 metres (10 ft) at a medium rate or to a small tree up to 5 m (16 ft) high. It prefers full sun. It is frost-sensitive and can be grown in USDA hardiness zones 8-11 and UK zone 9. The plant will grow in any type of soil that is deep and well-drained, including poor, rocky, alkaline or slightly acidic soils.

Uses

The fruit has a sour taste; dried and crushed, it is a popular spice in the Middle East, used especially in the spice mixture za'atar.

Editorial summary

The public source identifies “Rhus coriaria” as species of plant. This brief keeps that definition visible, then builds a research path around Rhus, coriaria and species.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current 205-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Rhus, coriaria and species providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Rhus coriaria”, the useful work is to connect “species of plant” to the records capable of establishing context and consequence.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 7, 2026. The linked authority identifier is Q159546.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
