Christmas Rose: How to Grow Helleborus Niger

The Christmas rose is one of the loveliest winter flowers you can grow. Its pure white, cup-shaped flowers open from December to February, often with a dusting of frost. You’ll find it in shops at Christmas as a gift plant. Treat it as a garden plant, not a houseplant, and it’ll come back every winter for years.

This guide is all about the Christmas rose, Helleborus niger. For Lenten roses and other hellebores, see our guide to growing hellebores.

What is a Christmas rose?

Despite its name, the Christmas rose isn’t a rose at all. It’s a hellebore, a hardy perennial related to buttercups. It grows about 30cm tall, with leathery, dark green leaves.

The flowers are white with a ring of golden stamens in the middle. They face outwards or slightly upwards, so you can see into them more easily than most hellebores. What look like petals are actually sepals. That’s why they last for weeks on the plant.

In the ground, it usually flowers from late December to February. Plants sold in December have been grown under cover to bloom in time for Christmas.

Gardener’s tip: An old story says the Christmas rose grew from a girl’s tears in the snow. She had no gift for the baby Jesus. It’s a lovely tale to share when you give one as a present.

Looking after a gift Christmas rose

Potted Christmas roses are popular presents. They’re often sold in a pretty pot cover beside poinsettias. Unlike a poinsettia, though, the Christmas rose doesn’t want to live indoors.

Here’s how to keep a gift plant happy:

1. Keep it cool. Stand it in the coolest bright room you have, such as a porch or a cool windowsill. Keep it away from radiators.
2. Keep it moist. Water when the top of the compost feels dry. Tip out any water left in the pot cover.
3. Enjoy it for a week or two. The warmer the room, the quicker the flowers fade.
4. Move it outside. Put it outdoors in a sheltered, shady spot, such as by the back door. Do this gradually if it’s frosty.
5. Plant it out. Plant it in the garden or a bigger pot in late winter or spring.

A gift plant is happiest in a cool, bright spot. Move it outside after a week or two.

Where to plant a Christmas rose

Christmas roses grow best in part shade, such as under deciduous shrubs or trees. They get winter sun when the branches are bare, and summer shade when the leaves are out.

They like rich, well-drained soil that holds some moisture in summer. Unlike many hellebores, they prefer neutral to chalky soil rather than acid soil. Heavy clay is fine if you dig in plenty of compost or leaf mould.

Plant them near a path or a window, where you’ll see the flowers in midwinter. A sheltered spot also keeps the white flowers cleaner. Our guide to plants for shade has ideas for planting partners.

How to plant a Christmas rose

Plant in autumn or spring, or straight after flowering if you’ve had it as a gift.

1. If it’s been indoors, stand it outside in a sheltered spot for a few days first.
2. Dig a hole twice as wide as the pot.
3. Mix plenty of compost or leaf mould into the soil you dug out.
4. Plant it at the same depth it was in the pot. Don’t bury the crown.
5. Firm the soil gently and water well.
6. Mulch around it with leaf mould or bark, keeping the mulch off the crown.

Space plants about 30 to 45cm apart. Christmas roses don’t like being moved once settled, so choose the spot with care.

Plant it in part shade under a deciduous shrub, with plenty of leaf mould dug in.

Warning: All parts of the Christmas rose are poisonous if eaten, and the sap can irritate skin. Wear gloves when you plant, cut or divide it, and wash your hands afterwards.

Growing a Christmas rose in a pot

The Christmas rose is a lovely pot plant for a shady patio or by the front door. Use a pot at least 30cm wide with drainage holes. Fill it with soil-based compost, such as John Innes No. 3, mixed with a few handfuls of grit.

Water regularly in spring and summer, as pots dry out fast. Feed with a general liquid feed once a month from spring to late summer. Move it to a bigger pot every few years. Our guide to plants for pots all year round suggests good partners.

Caring for a Christmas rose through the year

Christmas roses need very little looking after once they’re settled.

Watering. Water in dry spells, especially in the first summer. They don’t like to dry out completely.

Feeding. Mulch with compost or leaf mould each autumn. A sprinkle of general fertiliser in spring helps too.

Tidying. Cut off any tatty or spotted leaves at the base. Unlike Lenten roses, you don’t need to cut all the leaves off in winter. Just remove the worst ones.

Deadheading. Once the flowers turn green and tatty, cut the stems off at the base. Leave a few if you’d like seedlings.

Why are my Christmas rose flowers turning pink?

This worries lots of people, but it’s perfectly normal. As the flowers age, the white sepals often blush pink, then slowly turn green. It happens faster in cold weather and once the flowers have been pollinated.

The green flowers can stay on the plant for weeks while the seeds form. They still look lovely, in a quieter way.

White flowers turning pink and then green as they age is completely normal.

Christmas rose problems

Problem	Likely cause	What to do
No flowers	Young or newly moved plant, deep shade	Give it a year or two and a brighter spot
Dark blotches on leaves	Hellebore leaf spot, a fungal disease	Cut off and bin affected leaves
Flowers splashed with mud	Rain on bare soil	Mulch around the plant
Holes in new shoots	Slugs and snails	Use a ring of grit or wildlife-friendly slug traps
Wilting in a pot	Dry compost or vine weevil grubs	Water well and check the roots for white grubs
Flowers fade fast indoors	Room too warm	Keep it cool, then move it outside

Cutting Christmas roses for the vase

Freshly picked Christmas roses often droop within a day. These tricks help them last:

• Pick older flowers. Flowers that have started to form seed pods in the middle last much longer in water.
• Float them. Cut the flower heads off with a short stem. Float them in a shallow bowl of water. They’ll stay fresh for days on a Christmas table.
• Slit the stems. Make a long cut up the base of each stem before you put it in water.

Our guide to making cut flowers last longer has more tips.

Floating the flower heads in a shallow bowl keeps them fresh for days.

Common mistakes with Christmas roses

Keeping it indoors as a houseplant is the most common mistake. It’s a hardy outdoor plant and fades quickly in a warm room.

Expecting flowers on Christmas Day can disappoint. Plants in the ground often flower in January.

Planting the crown too deep can stop it flowering. Keep it at the same depth it was in the pot.

Letting it dry out in summer weakens next winter’s flowers. Water in long dry spells.

Moving it around the garden sets it back. Pick a good spot and leave it to settle.

Good partners for Christmas roses

Christmas roses look wonderful with other winter flowers. Plant snowdrops and winter aconites around them, with ferns and sweet box nearby. Our guide to winter-flowering plants has more ideas for the cold months.
