Helleborus hybridus ViV Rosa

Rosa is a variety of Oriental Hellebore with romantic winter flowers. Its simple flowers create transparency where white and pink blend together to form a magical spectacle under the mild winter sun. This Rose of Lent blooms in January and February, bringing light to the garden with its flowers, highlighted by the dark green evergreen foliage. This perennial forms a dense and compact clump of about forty centimetres in all directions. It can be grown in a large pot to decorate a balcony, as well as in the ground in the garden where it requires a shady exposure and a neutral to limestone soil, but it tolerates some acidity. It is hardy enough to be planted in almost all regions.

Hellebore Rosa is a member of the Ranunculaceae family, which includes about sixty genera and around 2500 species. Many of them are poisonous and contain substances which are toxic if ingested - a natural protection to prevent them from being grazed by herbivores. Despite this, they are valuable plants in the garden, as many genera are highly ornamental thanks to their remarkable flowering, such as Anemones, Ranunculus, Trollius, Aconites, and many others, including Clematis. The species Helleborus orientalis is native to Greece, Turkey, and the central and eastern Caucasus. It is a perennial plant that hybridizes very easily with other species, resulting in many hybrids with varied colours and forms through random sowing which are rarely given variety names. They are distinguished by their shape and colour. Hellebore is a hardy plant that can withstand temperatures down to -15°C (5°F), naturally growing in forests, thickets, and clearings up to 2,000 m (2,187 yards) altitude.

Rosa is a variety distributed by a Belgian company specialising in the in vitro selection and multiplication of Hellebores. This mode of propagation ensures the perfect transmission of genes and the stability of the species, which are all perfectly identified by their name. Rosa is part of a large collection of hybrids selected for their compactness and floribundity. This variety forms a clump 40 cm (16in) high and of equivalent width, with a tight and dense habit, capable of forming beautiful flower pots on your balcony or terrace. If you plant it in the garden, choose a semi-shaded exposure to protect it from scorching sun. In the north the shade of deciduous trees will be perfect, the mild winter sun will not harm it when the leaves of the trees have fallen. In the south, it is better to shelter it under evergreens, such as Chinese Privet (Ligustrum lucidum), a small tree with fragrant flowering in late summer and decorative fruits until winter. The vegetation of this Hellebore consists of palmate, slightly dentate, dark green and shiny, evergreen basal leaves which live only 8 months and are regularly replaced by new leaves.

Rosa blooms at the very beginning of the year and flowers for several weeks, lighting up the garden with its flowers, which are very visible during these generally dim days. To enjoy them to the fullest, choose a location where the low winter sun can illuminate the translucent petals. This well-known light effect will be easier to achieve if planted in a pot that you can easily place in the right spot on a table or other support. The five diaphanous petals, which overlap at their junction, will create beautiful transparency when crossed by the sun. Their white background is adorned with small pink spots, the effect of which accumulates where the petals overlap, thus reinforcing the two-tone aspect of these charmingly romantic flowers. Carried by sturdy stems, these corollas bloom vertically, as in most varieties of Hellebores, or even slightly inclined downwards, to let the water slide off like an umbrella, avoiding accumulation in the centre that could cause rotting. Hellebores do not like to be moved once established, with young plants sometimes taking time to bloom, so be careful to choose the right location.
This perennial adapts to neutral to moderately limestone soils, or slightly acidic soils, preferably rich and moisture-retaining, although an established plant can tolerate dry conditions. Make sure that the soil is well-drained, as Hellebores do not appreciate excess water in winter. It will be happy under a leafy tree, which will let the winter sun through, but protect it from the bright summer sun. Its compact habit allows it to make a superb flowering pot to decorate a balcony or terrace.

Helebores are among the most beautiful flowers in the garden, especially since they grace us with their flowering during a gloomy season. Rosa honours the genus with its light flowers, whose charm will not leave anyone indifferent. You can plant it alongside other varieties of Hellebores that will allow you to enjoy varied blooms in terms of colour and form from autumn to early spring. To further extend the flowering season, add some Epimedium plants to your semi-shaded flower bed. These persistent perennial cousins of Berberis, have graceful flowers with sculptural shapes and superb colours that will enchant your spring. In the background, Hydrangea quercifolia Munchkin or Oakleaf Hydrangea will delight you with its flowers throughout summer and into autumn. This compact shrub, tolerant of limestone, has long white inflorescences that turn pink as autumn approaches, while the decorative foliage with its original design takes on superb autumnal colours.
