Cistus ladanifer is a species of flowering plant in the family Cistaceae. It is native to the western Mediterranean region. Common names include gum rockrose, [1] labdanum, [1] common gum cistus, [1] and brown-eyed rockrose. [2]
It is a shrub growing 1–2.5 m (3 ft 3 in – 8 ft 2 in) tall and wide. The leaves are evergreen, lanceolate, 3–10 cm long and 1–2 cm broad, dark green above and paler underneath. The flowers are 5–8 cm diameter, with 5 papery white petals, usually with a red to maroon spot at the base, surrounding the yellow stamens and pistils. The whole plant is covered with the sticky exudate of fragrant resin, the source of labdanum, used in herbal medicine and perfumery.
C. ladanifer is particularly well suited to the Mediterranean climate, standing both long summer droughts and cold weather. It is an extremely aggressive plant which has taken over much of former farmland and grasslands in the mountain regions of central Spain and much of southern Portugal. In Spanish it is known as Jara pringosa meaning "sticky shrub". In Portuguese it is known as "esteva". It has been found to have mycorrhizal associations with Boletus edulis , Boletus rhodoxanthus , and Laccaria laccata . [3]
The wide distribution and morphological variation of C. ladanifer across northern Africa, the Iberian Peninsula, and southern France has resulted in the recognition of three sub-species: subspp. ladanifer, sulcatus, and africanus.
C. ladanifer is placed within the C. salvifolius group within the white and whitish pink flowered clade of Cistus species. [7]

Phylogenetic and divergence dating methods found that C. ladanifer diverged during the Pleistocene, long after the opening of the Strait of Gibraltar around 5 mya, which supports a hypothesis of dispersal for this species. [11] Although its seeds fall close to the maternal plant, [12] C. ladanifer may have successfully dispersed due to its preference for disturbed habitats.
It is a popular ornamental plant, grown for its strongly resin-scented foliage and conspicuous flowers. Its leaves yield a fragrant oleoresin known as labdanum, used in perfumes, especially as a fixative.[ citation needed ] (Not to be confused with "Laudanum", another name for tincture of opium).
This plant has gained the Royal Horticultural Society's Award of Garden Merit. [13]
The Cistaceae are a small family of plants known for their beautiful shrubs, which are profusely covered by flowers at the time of blossom. This family consists of about 170(-200) species in nine genera that are not very distinct, distributed primarily in the temperate areas of Europe and the Mediterranean basin, but also found in North America; a limited number of species are found in South America. Most Cistaceae are subshrubs and low shrubs, and some are herbaceous. They prefer dry and sunny habitats. Cistaceae grow well on poor soils, and many of them are cultivated in gardens.
Cistus is a genus of flowering plants in the rockrose family Cistaceae, containing about 20 species. They are perennial shrubs found on dry or rocky soils throughout the Mediterranean region, from Morocco and Portugal through to the Middle East, and also on the Canary Islands.
Cistus creticus is a species of shrubby plant in the family Cistaceae. Though it usually has pink flowers, of 4.5–5 cm diameter, this species is very variable. It is widely known as a decorative plant. It is frequently called "Cistus incanus".
Cistus monspeliensis is a species of rockrose known by the common name Montpellier cistus or narrow-leaved cistus. It is native to southern Europe and northern Africa, in the Mediterranean forests, woodlands, and scrub ecosystems of matorral—maquis shrublands.
Cistus laurifolius, commonly called laurel-leaf cistus, laurel-leaved cistus or laurel-leaved rock rose, is a species of highly branched flowering evergreen shrub native to some areas around the Mediterranean.
Cistus albidus, the grey-leaved cistus, is a shrubby species of flowering plant in the family Cistaceae, with pink to purple flowers, native to south-western Europe and western north Africa.
Cistus asper is a shrubby species of flowering plant in the family Cistaceae with purple-pink flowers. It was first described in 2005 and is endemic to El Hierro in the Canary Islands.
Cistus chinamadensis is a shrubby species of flowering plant in the family Cistaceae, with purple-pink flowers, first described in 1991. It is endemic to the Canary Islands, where three subspecies occur on three separate islands. The species has been assessed as endangered in the IUCN Red List, being known only from small separated areas and facing a variety of threats.
Cistus clusii is a shrubby species of flowering plant in the family Cistaceae, with white flowers, native to south west and south central Europe and north Africa. It has been wrongly called Cistus libanotis by many authors.

Cistus horrens is a shrubby species of flowering plant in the family Cistaceae, with purple to pink flowers. It is endemic to Gran Canaria in the Canary Islands. First described as a species in 2004, it was previously identified as Cistus symphytifolius, which it resembles.
Cistus inflatus is a shrubby species of flowering plant in the family Cistaceae, often known as Cistus psilosepalus, although this name is a synonym of the hybrid Cistus × laxus. It has white flowers.
Cistus ocreatus is a shrubby species of flowering plant in the family Cistaceae, with purple-pink flowers. It is sometimes treated as synonymous with Cistus symphytifolius or as its subspecies C. symphytifolius subsp. leucophyllus. Its name is sometimes spelt Cistus ochreatus. It is endemic to Gran Canaria in the Canary Islands.
