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.
