Viburnum tinus Gwenllian

Viburnum tinus 'Gwenllian' is a variety of laurustinus, selected in England by Kew Gardens for its compact and wide habit, as well as for its generous flowering and beautiful colour; qualities that make it well suited to container gardening and ornamentation in small gardens. It is a bushy shrub that is adorned with dark green glossy leaves, which are decorative throughout the year, and its delicate flowering extends from autumn to early spring. Its floral buds, a lovely deep pink, open into white-pink flowers. A charming, robust, and carefree plant that adapts to all exposures, even shade, and all soils, even very limestone and dry ones in summer.

The Gwenlian laurustinus belongs to the Caprifoliaceae family, or Adoxaceae according to classifications. The Viburnum tinus species is native to the Mediterranean basin, where it is found in undergrowth, forest edges, scrub vegetation, and scrubland. It is a relatively cold-resistant evergreen shrub (down to -15 °C (5 °F) for short periods for an adult specimen), which adapts to a wide range of soils as long as they are not too wet or waterlogged in winter. Its fruits are consumed by birds, who 'sow' the plant under trees that they use as perches, as it is typically an undergrowth shrub that perfectly tolerates the root competition from other trees.

The slow-growing Viburnum tinus Gwenllian forms a bushy, rounded, and wide shrub, branching from the base. It will reach approximately 1.5 m (5 ft) in all directions. Its branches bear narrower and more elegant leaves than those of the type species. They are single, elliptical and pointed at their tips, measuring 5 to 8 cm (2 to 3 in) long and 3.5 cm (1 in) wide. With a leathery texture, they are slightly shiny and persist throughout winter. In spring, the young leaves are a soft green and then turn dark green when mature. Flowering often begins in autumn, depending on the region. At the tips of one-year-old and older branches, inflorescences in clusters form, resembling small round and slightly bulging bouquets, 5 to 6 cm (2 in) in diameter. They are densely covered with floral buds, a fairly bright pink with a salmon hue, which remain decorative throughout winter. These buds open from February to April, into small 2 to 3 mm (0.1 in) diameter flowers with 5 white petals that are pink on the reverse. These slightly fragrant flowers are highly visited by bees. After pollination, the flowers give way to oval berries measuring 4 to 5 mm (0.2 in) long, with a metallic blue-black colour, containing a single seed, carried by pink stalks. In the laurustinus, the seeds need to be freed from their pulp in order to germinate, a step that occurs naturally in the digestive system of birds.

Truly easy to grow, undemanding, space-saving, and covered in leaves throughout the year, the Gwenllian laurustinus is an excellent shrub for terraces or small gardens. Like Mexican orange trees, myrtles, and small winter-flowering shrubs, it is perfect for bringing life to the garden during the shortest days of the year. It is also an essential plant for creating the evergreen structure of a garden. Excellently tolerating shade and root competition, laurustinus can be used to arrange undergrowth areas alongside Sarcococca and sacred bamboos, for example. As it tolerates repeated pruning very well, it can be used in topiary art to create original shapes within its vegetation.
