Prunus lusitanica
Distribution
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.
The species was first scientifically described by Linnaeus in Species Plantarum in 1753. Its specific epithet lusitanica means of Lusitania, the Roman name for Portugal.
Description
Prunus lusitanica is an evergreen shrub or small tree growing to 3-4m tall. It will grow to 20 foot high according to some references. The bark is blackish-brown, The leaves are alternate, oval, 7–12 cm long and 3–5 cm broad, with an acute apex and a dentate margin, glossy dark green above, lighter below. 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.
Three subspecies are accepted:
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, and 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 and defecate the fruits 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.
