Prunus laurocerasus 'MINIREDIA' cherry laurel - standard tree
Prunus
The genus Prunus is quite extensive and, above all, remarkably diverse – it includes around 350 different species, some of which you would hardly place in the same group at first glance. Its representatives occur from Asia through Europe and North Africa to North America. The genus comprises trees and shrubs valued mainly for their abundant and attractive flowering, as well as species with delicious edible fruits, and in this particular case an evergreen species whose persistent foliage becomes especially important during the dormant season, when most other woody plants are leafless. This species is known as cherry laurel (Prunus laurocerasus) and originates from regions around the Black Sea, the Caucasus, and northern Turkey, where it grows in submontane forests and on moist, shaded slopes. Its glossy, leathery leaves resemble those of true laurel, and this similarity that gave rise to its name – lauro‑cerasus, meaning “laurel cherry.” It reached Europe as early as the 16th century and, thanks to its frost hardiness, is today one of the most important evergreen woody plants even in Central European climate.
Cherry laurel was scientifically described in 1753 by Carl Linnaeus in his seminal work Species Plantarum, where it received its still accepted name Prunus laurocerasus. A later, now obsolete name, Laurocerasus officinalis, nevertheless points to a much older history of cultivation and use. A laurel‑like plant identified with cherry laurel is already mentioned by Theophrastus, Dioscorides and Pliny the Elder, who noted its unusual properties. From the leaves of cherry laurel, a distillate known as aqua laurocerasi was prepared and, when used with due caution, employed as a sedative – hence the Latin epithet officinalis, meaning medicinal. Historically and with documentary support, cherry laurel, its introduction, and its first cultivation in European gardens can be traced to the year 1576. This date fits well within the period of diplomatic missions between the Ottoman Empire and the Habsburgs, when seeds, cuttings, and young plants of previously unknown species were brought from Constantinople to Central Europe through networks associated with figures such as the imperial envoy David Ungnad (1530–1600) and the botanist Carolus Clusius (1526–1609). The transfer of newly discovered plants was regarded as a gift equal in value to gold, works of art, or archaeological finds, and represented an important expression of learning, prestige, and practical knowledge of the natural world.
Miniredia is a slow‑growing dwarf cherry laurel variety with evergreen, glossy, dark green leaves measuring 7–8 cm in length and 4–5 cm in width, broadly elliptic in shape. In spring, the young foliage emerges in a striking amber‑orange colour, similar to cultivars such as ETNA® or BONAPARTE®. On older plants, upright racemes composed of small white flowers appear in April; these bloom profusely and emit a strong, sweet fragrance reminiscent of lilac. After pollination, attractive glossy black fruits develop, which are a favourite food source for birds. The fruits themselves are not poisonous; only the kernels of unripe, hard fruits contain trace amounts of the same substance found in bitter almonds, and they would need to be thoroughly chewed to cause discomfort. The cultivar Miniredia was introduced in 2021 by the French nursery Hortival Diffusion (Minier). It is a hybrid of the cultivar Caucasica Nana and a non‑commercial seedling N4281 from 2007, bred by Patrick Pineau. It is protected by the following patents: PP34406 (USA – 2022), 35416 (UK – 2022), and 60082 (EU – 2022).
A single‑stem, or standard tree, is an attractive way to grow evergreen woody plants. It offers permanent greenery at a higher level than shrubs branching from the base, allows free passage beneath the crown, and creates an airy, bright space for underplanting. It also provides better screening from unwanted views from neighbouring windows, as the main foliage mass sits higher than in shrub forms. The eventual height depends on how the plant was trained: non‑grafted trees formed by removing side shoots along the stem reach the same height as shrub forms of the given species or cultivar, while grafted trees may exceed this by the height of the rootstock. They are commonly offered as half‑standards with a stem of around one metre, three‑quarter standards, or full standards with the crown set at approximately two metres. Like all single‑stemmed trees, they require firm staking for the first three years and a clean area above the roots, free of lawn and weeds.
Cherry laurels require moist but well‑drained soil, ideally acidic to neutral and rich in nutrients. They do not tolerate compacted, heavy clay, muddy, or permanently waterlogged soils. They are sensitive to lime in the soil, which most commonly manifests as chlorosis – the leaves lose their green colour and the vein pattern becomes pronounced. Similar symptoms may also occur in cases of nutrient deficiency. In both situations, the application of magnesium sulphate (Epsom salt), organic fertilisers, or adjustment of soil pH towards a more acidic reaction is beneficial. They tolerate pruning of any intensity and respond particularly well to rejuvenation pruning into old wood, from which they readily regenerate. The best time for pruning is in spring after the risk of frost has passed; shaping cuts are carried out in mid‑summer. Because they retain their leaves year‑round – even in winter – and continuously transpire water, they require an adequate supply of moisture. Until a sufficiently deep root system develops, it is advisable to water them at least once a month during dry winters to prevent dehydration and subsequent leaf scorch caused by strong winter sun. To retain moisture and protect against temperature fluctuations, year‑round mulching is strongly recommended. The ultimate frost hardiness of this cultivar has not yet been definitively established, but it is estimated to tolerate at least −24 °C, similar to its parent plants.
