Prunus lusitanica

Prunus lusitanica is an evergreen shrub or small tree growing to 3-8m tall (though it can reach 15-20m in cultivation). The bark is smooth and dark-grey. ==Distribution and habitat==

It occurs in the western Mediterranean Basin, France, Spain, and Portugal, and Macaronesia, Azores, Canary Islands and Madeira. 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. ==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. ==Subspecies==

Three subspecies are accepted: • '''Prunus lusitanica subsp. hixa''' (Willd.) Franco. Canary Islands and Madeira. ==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. 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. It has gained the Royal Horticultural Society's Award of Garden Merit. ==Toxicity==

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