Helleborus hybridus (orientalis) ViV Olivia

The Oriental Hellebore Olivia is a very floriferous compact variety. Flowering from November, this Lenten Rose produces abundant single flowers in a bright cream-white colour, enhanced by the dark green evergreen foliage. It is a robust and hardy perennial that is easy to grow in all regions, even in heavy soil, although it prefers humus-bearing soils. It will create superb borders in shaded areas, and its limited growth also allows it to be easily grown in pots. Plant it under the shade of deciduous trees, where it will flower at the base in autumn.

The Hellebore (or ellebore) ViV 'Olivia' is a member of the Ranunculaceae family, which includes about sixty genera and around 2500 species. Many of them are poisonous beauties, meaning they contain toxic substances if ingested (natural protection to prevent them from being grazed by herbivores). Despite this, they are appreciated plants in the garden for their often highly ornamental flowering, as seen in Anemones, Buttercups, Trollius, Aconites, and many others, not to mention Clematis. The cultivar Olivia is a Belgian hybrid derived from the cross-breeding of Helleborus x ericsmithii. The parents are Helleborus niger, the true Christmas Rose, which comes from the Alps, and Helleborus x sternii, itself a hybrid obtained by crossing H. argutifolius, native to Corsica and Sardinia, and H. lividus, from the Balearic Islands. Olivia is a compact perennial, forming a clump 40 cm in height and width, which will thrive in the light shade of deciduous trees or even in denser shade, such as that generated by conifers. Its foliage consists of palmate basal leaves, slightly dentate, leathery, dark green, and glossy. These are evergreen leaves in winter, which only live for eight months and are regularly replaced by new leaves.
This very floriferous Hellebore begins flowering as early as November. Pink buds are abundantly produced and open up to reveal very light cream-white corollas. They consist of five rounded sepals that imitate petals, while the actual petals resemble small cones folded in on themselves. Light green in colour, they form a central circle that surrounds a cluster of protruding light yellow stamens. The corolla is sometimes slightly tinged with pale green, and the low winter sun creates beautiful transparencies as it shines through. The flowers succeed each other and abundantly renew until January, enchanting the garden during this often somewhat gloomy season. If they are positioned vertically or inclined downwards, allowing water to slide off like an umbrella, it protects the heart from rotting. Hellebores do not like to be moved once established, and young shoots occasionally take time to flower. Therefore, be sure to choose their location carefully when planting.
This perennial adapts to neutral to moderately alkaline (limestone) soils or even slightly acidic soils, preferably rich and retaining some moisture, although an established plant can withstand dry conditions well. It will thrive under leafy trees, allowing winter sun to pass through while protecting it from the intense summer sun. It is a relatively easy plant to succeed with and can also be grown in pots on your terrace due to its compact habit. In this case, monitor the potting soil to water it in a timely manner and prevent it from drying out.

Hellebores are unmatched in brightening up the dark days of autumn and winter. To enhance this effect, plant evergreen shrubs with variegated foliage alongside them, bringing light to the heart of winter. Standing at only 50 cm tall, Euonymus fortunei Goldy is a dwarf spindle tree that will coexist with your Hellebore without smothering it. Its extremely golden foliage is remarkably bright under a grey sky. Its cousin, Euonymus japonicus White Spire, forms a narrow column up to 1.50 m in height, with green foliage strongly variegated with white, similarly bringing brightness to a winter border. In mild climates, also consider Hebe Orphan Annie, a shrubby Veronica that forms a compact dome only 60 cm tall. Its delicate foliage is green-bordered with cream-white and tends to turn golden yellow in cold weather. In addition, it has a superb flowering of small magenta-pink spikes that extend from May to September.
