The clumps are beautiful, the flowers splendid, with a colour of rare intensity! But the root ball had completely filled the pot (there was barely a gram of substrate left!!) I hope that planting them straight away and the rain that followed for several days will allow them to settle in, because I would be extremely disappointed to lose them!

Description
Oriental Hellebore Luisa is one of the few varieties in this group that has double, almost black flowers, with hints of purple. This very dark Christmas Rose is adorned with a contrasting yellow stamen. It is a robust and very hardy perennial, easy to grow in all regions, even in heavy soil. Pair it with pink, white, apricot, solid or speckled blooms, under bushes, in woodland or to decorate the north side of the house. Christmas roses also make beautiful flowering pots that brighten up gloomy winter days.
Hellebore Luisa belongs to the buttercup family. Its ancestor Helleborus orientalis is native to Greece, Turkey, and central and eastern Caucasus. It is a perennial plant that readily hybridizes with other species, resulting in hybrids of various colours and forms. These hybrids are rarely given variety names and are distinguished by their shape and colour. Oriental Hellebore is a hardy plant that can tolerate temperatures as low as -15°C (5°F), naturally growing in forests, thickets, and clearings up to 2,000 m (6.600 ft) above sea level. The Luisa cultivar forms a compact and leafy clump about 30-40 cm (12-16in) in all directions. It has palmate evergreen basal leaves, slightly toothed, dark green and glossy, 30 to 40 cm (12 to 16in) long, composed of 7 to 9 leaflets. They only live for 8 months and are regularly replaced by new leaves.
Between January and February, a bouquet of very-double, slightly inclined cup-shaped flowers about 4 to 5 cm (2in) in diameter forms with several rows of petals, characteristic of this group of hybrids. They are inclined downwards, allowing water to slide off like an umbrella to protect the heart of the flower from rotting. The Hellebore does not like to be moved once established, and young plants may take some time to flower. The seeds are sown by ants.
Use hellebores like elements of an ancient tapestry, mixing them with more vibrant woodland plants. They look great planted near Pieris, Sarcococcas, under conifers (especially in windy sites), surrounded by primroses, wood anemones, bleeding hearts, or spring-flowering bulbs and snowdrops. You can also accompany them with ferns and shade-loving irises to create a beautiful contrast a little later in the season. Christmas roses can also be planted in groups, like a bouquet, near the entrance of the house, in shaded areas, to fully enjoy their early flowers. They are suitable as cut flowers and in borders, beds, or containers. Over time, Hellebore flowers do not wilt like the majority of other flowers, but they dry up.
Each seed-sown hellebore has a unique flower colour: thus, slight colour variations may exist between two plants, which is normal and inevitable. However, if the difference is too significant and distorts the desired effect, we will refund or replace the affected plant.

Planting and care
Hellebore Luisa grows in any neutral to acidic, rich, light or clayey soil, in partial or light shade, sheltered from cold and dominant winds. Avoid direct sunlight during the hottest hours. This perennial can be planted from early autumn to spring, between February and April. It thrives in deeply cultivated soil mixed with organic matter. To feed, use bone meal or another organic fertilizer. Water the plants well then add a layer of mulch 2 to 5 cm (1 to 2in) thick. Regularly remove faded leaves to improve flowering. Be sure to plant at a distance of 30 to 40 cm (12 to 16in) from each other to promote their development. Hellebores do not tolerate stagnant water, as it can cause them to rot.
The crowns should not completely dry out in summer. Hellebores can be affected by a fungal disease transmitted by aphids, called black spot. Remove old leaves from deciduous species or stained leaves from evergreen species when flower buds appear. Remove faded flowers after seeding. They can also suffer from grey rot or die from collar rot. This often occurs due to poor growing conditions, in excessively wet situations.
On a balcony or terrace, plant them in pots that are 4 to 5 times larger than they are, as they need space to develop their root system. Most hellebores can withstand temperatures down to -15°C (5°F) without suffering, allowing them to adapt to almost all regions.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
