Prunus lusitanica, the Portuguese laurel cherry [4] or Portugal laurel, [5] is a species of flowering plant in the rose family Rosaceae, native to the Iberian Peninsula, Morocco, the Macaronesian archipelagos, and the French Basque Country. [6] [7] [8]

Contents

The split between the two subspecies (subsp. azorica, found in the Azores, and subsp. hixa / subsp. lusitanica, found elsewhere) is dated around the Pliocene. [9]

Description

Prunus lusitanica is an evergreen shrub or small tree growing to 3-8m tall (though it can reach 15-20m in cultivation). [10] [11] [12] [13] The bark is smooth and dark-grey. [10] The leaves are alternate, oval, 7–15 cm long and 3–5 cm broad, [10] with an acute apex and a dentate margin, glossy dark green above, lighter below. [12] They superficially resemble those of the bay laurel, which accounts for its often being mistaken for one.

The flowers are small (10–15 mm diameter) with five small white petals; they are produced on erect or spreading racemes 15–25 cm long in late spring. The fruit is a small cherry-like drupe 8–13 mm in diameter, green or reddish green at first, turning dark purple or black when ripe in late summer or early autumn. [10] [14]

Ripe fruit

Prunus lusitanica is rare in the wild, found mainly along mountain streams, preferring sunshine and moist but well-drained soils. It is moderately drought-tolerant. It reproduces either sexually (the most successful method) or asexually by cloning from shoots. [15]

Name

The species was first scientifically described by Linnaeus in Species Plantarum in 1753. Its specific epithet lusitanica means "of Lusitania", referring to the Roman name for Portugal. [16]

Subspecies

Three subspecies are accepted: [3]

Cultivation

Prunus lusitanica is grown as an ornamental shrub and is widely planted as a hedge and for screening in gardens and parks. It is introduced and locally naturalised in the temperate zone in northern France, Great Britain, Ireland, New Zealand, Western Canada- including the southern BC Mainland and Vancouver Island From Victoria Up Island through the Cowichan, Nanaimo and Parksville as well as the western United States in California, Oregon and Washington State.[ citation needed ]

Similar to its relative Prunus laurocerasus , P. lusitanica has been recognized by some botanists and land managers in both western Washington and Oregon as invasive. It is thought to have spread from cultivated areas into natural areas by birds who consume the fruit and then defecate the seeds away from the source plant.[ citation needed ]

It has gained the Royal Horticultural Society's Award of Garden Merit. [18]

Toxicity

The leaves of Prunus lusitanica contain cyanide and will release this into the environment if burnt [19] or if crushed. [20] The fruit is somewhat edible if fully ripe, but if it is bitter, it is toxic and should not be eaten. [21]

<span class="mw-page-title-main">Macaronesia</span> Archipelagos off the Atlantic coasts of Africa and Europe

Macaronesia is a collection of four volcanic archipelagos in the North Atlantic, off the coasts of Africa and Europe. Each archipelago is made up of a number of Atlantic oceanic islands, which are formed by seamounts on the ocean floor whose peaks have risen above the ocean's surface. They are grouped politically into four groups- the Azores and Madeira archipelagos are part of Portugal, the Canary Islands are part of Spain, and the Cape Verde islands comprise their own sovereign nation. Politically, the islands belonging to Portugal and Spain are part of the European Union. Geologically, most of Macaronesia is part of the African tectonic plate. The Azores are located in the triple junction between the Eurasian, North American and African plates.
