Common gum cistus

The common gum cistus, <em>Cistus ladanifer</em>, is a flowering shrub belonging to the family Cistaceae. It is typically found across a broad range of countries including Cyprus, Italy, Portugal, South Africa, and the United States, reflecting both its native distribution and introduced occurrences. Native primarily to the Iberian Peninsula and the Mediterranean region, this species is well known for producing labdanum, an aromatic resin used in perfumery. <em>Cistus ladanifer</em> typically grows in dry, rocky, or sandy soils in scrubland and garrigue habitats, where it can form dense thickets. Its large white flowers with a distinctive dark spot at the base of each petal are a recognizable feature. No dietary information has been provided for this species. Biological traits of this species remain poorly documented in the scientific literature.
