Prunus laurocerasus – Cherry laurel

  Cherry laurel is a species native to Europe and western Asia. It is an evergreen shrub growing up to around 6m by 10m. It flowers from April to June and its seeds ripen in September. The flowers are hermaphrodite (have both male and female organs) and are pollinated by bees. The plant can grow in most types of soil, from light sandy soils to heavy clay soils, however it prefers moist soil. It can grow in heavily shaded areas such as woodland with dense canopies, and can tolerate strong winds but not maritime exposure. All parts of the plant contain hydrogen cyanide, this toxin is found mainly in the leaves and seed but is usually present in too small a quantity to do any harm, however any very bitter seed or fruit should not be eaten.
  The plant has some medicinal purposes and hydrogen cyanide, in small quantities, is known to stimulate respiration and improve digestion. It is also said to be of benefit to the treatment of cancer. However, if used excessively it can cause respiratory failure and even death.

  Its fruit is about 8mm in diameter and contains one large seed in the centre. Its fruit can be eaten by humans but are known to be potentially dangerous when not ripe.

  The species I have pictured has been planted in a park amongst other shrubs and appears to compete successfully with other species of shrub like buddlea davidii and some larger trees.
