Depending on the variety, plant hellebores in full or partial shade at the front of a border. They can be grown in pots in a compost with a loam basis, but they thrive in rich, well-drained soil.
When to plant hellebores
As long as the soil is not frozen, hellebores can be planted at any time of the year. The majority of hellebores are listed for sale from late winter to early spring when they are in bloom, but you might locate one in a garden center’s clearance section in the summer that you can plant with no issues. Keep in mind that hellebores detest being moved after being planted, so avoid doing so.
How to plant hellebores
Hellebores should be planted in the same way as other perennials, with a spadeful of garden compost and a sprinkle of mycorrhizal fungi to aid in the plant’s establishment. Water thoroughly and gently press in.
Watch Monty Don’s instructional video on planting and growing hellebores to learn about planting depth, soil preparation, and how to prevent leaf spot disease. Additionally, Monty discusses how to select the best flowers for immediate effect and displays the variety of his collection of hellebores:
How to care for hellebores
When blossoms and new foliage appear, trim back the thick, leathery leaves, and mulch the plants every year with well-rotted compost or manure. Once established, hellebores struggle to be moved, therefore try to avoid doing so.
How to propagate hellebores
Avoid dividing hellebores since they struggle to be transported. In order to develop new plants for nothing, gather ripe seed and sow it into modules. Alternately, allow the hellebores in your garden to self-seed. By letting them self-seed at random, you’ll produce a hodge-podge of various colors and flower shapes; you might even develop your own new hybrid! No hellebore seedling will be true to its parents.
Growing hellebores: problem-solving
Leaf spot, a fungus infection that causes unattractive brown and black patches on the leaves, is the major foe of hellebores. When you see damaged foliage, remove it.
Here, Monty Don shows how to recognize hellebore leaf spot and describes how to prevent it from spreading to other plants:
Advice on buying hellebores
- Garden centers sell hellebores, but you can get a broader selection at specialized nurseries and online
- Avoid double-flowered hellebores if you are growing for bees because single-flowered plants are the best for pollinators.
Are hellebore plants toxic when touched?
I was pleasantly delighted to see that I suddenly have not two but three colors of hellebores in the landscape this year while surveying the garden for tasks I’ll need to complete.
Hellebores (Helleborus) have been discussed previously. I’ve already recounted that many years ago, I was given a few sets of plants by someone who was donating them to the newspaper’s plant sale. One of them, I’m fairly certain, is a green hellebore (H. viridis). The “green” refers to the creamy-white, somewhat green-tinged flower petals, particularly on the inside of the petals.
The other is the Lenten Rose, also known as Helleborus x hybridus or H. orientalis, depending on the source. It appears that all Helleborus x hybridus are H. orientalis, but not all Helleborus x hybridus are H. Orientalis.
My shade bed’s hellebores have been in flower since late January. But because of the rain, I haven’t had the chance to truly go outside and enjoy them.
I am working on a barter with my younger brother in Catawba County along with deciding which garden task to complete next.
In exchange for some lily of the valley, I’ll give him some hellebores and ferns (Convallaria majalis). Long ago, at the old house Scott currently resides in, my grandma planted her lily of the valley close to the clothesline. He asserts that the lily of the valley population is poised to engulf that portion of the property.
The sizable cluster of Lenten Rose that my fellow garden enthusiast gave me has consistently blossomed in a rich crimson. The fresh clump is a wonderful shade of soft pink. I’ve been following its growth from a seedling to a fully grown plant. The blooming period for new hellebores might be at least three years. The wait was worth it for this one.
Hellebores should technically be moved in the fall. However, I can safely relocate the tiny seedlings I’ll be gathering in the spring.
Take care if you have any hellebore plants and intend to move on your own. The Ranunculus, or buttercup, family includes hellebores. When handled, they are poisonous and can result in contact dermatitis.
You don’t want to inadvertently consume any of the plant. Despite the fact that the plant was historically used to cure depression, my research materials also state that the plant’s extract can have negative side effects. I’m confident that the excessive nausea, vomiting, and diarrhea it induces would temporarily distract anyone from their despair.
Set your transplants in a shady area with well-drained soil. Once established, hellebores are fairly forgiving, although you shouldn’t actually try to force them into a sunny border.
The moment has come to apply some general fertilizer and/or compost around any existing hellebores in your landscaping if you are satisfied with their current placement. To maintain this dependable perennial’s aesthetic appeal in the landscape after blooming has finished and the petals have gone, around June, you can remove any dead or ailing leaves.
Why are hellebore plants used?
The herb known as white hellebore was historically employed as poison in ancient Rome. An extract was then employed as an arrowtip poison.
The bulb and root are utilized in the production of pharmaceuticals despite major safety issues. Cholera, gout, and high blood pressure are all treated using white hellebore.
For herpes outbreaks, white hellebore can occasionally be administered directly to the afflicted area.
White hellebore is employed as a pesticide in the manufacturing process to combat mosquitoes and flies.
Is hellebore a perennial plant?
Hybrid hellebores can tolerate a broad range of growth situations, but they thrive in rich, moist, but well-draining soil when planted in partial shade. Hellebores are rather simple to grow and, as perennials, will bloom for a number of years.
Hellebore planting tips:
- To properly enjoy the downward-facing blooms of hellebore plants, many gardeners prefer to put them on a hillside or in raised flower beds. Here’s a great illustration of this planting technique: A box of winter jewels.
- Shake off the potting soil and untie any constrained roots before transplanting hellebores straight from their nursery containers.
- Planting hellebores too deeply can prevent them from producing flowers, so take care. Make sure the plant’s crown is barely visible above the dirt.
Are hellebores sun or shade plants?
- Hellebores thrive in slightly shaded, evenly moist, well-drained soil.
- Long dry spells should be adequately hydrated; once established, they are drought-tolerant.
- Hellebores thrive in soil that has been greatly improved by organic matter.
- The Helleborus x hybridus (formerly known as Helleborus orientalis) hybrids prefer a soil pH that is close to neutral or even alkaline; if your soil is excessively acidic, add lime.
- The Christmas Rose (H. niger) may take some time to establish itself; to speed things along, consider adding some magnesium to the environment in the form of Epsom salts or dolomitic limestone.
- Early in the spring, apply a little amount of balanced, granular fertilizer to the plants.
Why are hellebore prices so high?
Why are hellebore prices so high? Because it can take these flowers three to five years to blossom and because producers typically only sell blooming plants, they are typically highly expensive.
Do hellebores reproduce?
A hellebore will produce anywhere between two and ten divided plants. Plant the divided plants as soon as possible, taking care to prevent the roots from drying out. Plant them in well-prepared, well-drained soil.
Who or what consumes hellebores?
Slugs have a significant propensity toward hellebores. These ghastly insects not only eat the foliage, but they can even climb up the stalks and eat the blossoms.
Slugs and snails can be removed in a variety of ways, such as by hand-picking the slithery gastropods and feeding them to your chickens or by wasting expensive beer supplies in traps.
Slug Gone, a distinctive woolen product from the UK that is offered by Arbico Organics, can also deter them.
Does mice consume hellebore?
Hellebore illness is a terrible and fatal condition. Black streaks and patches in the leaves and flowers are the first signs of black death. Helleborus net necrosis virus has now been identified as the cause of this. The important information for gardeners is that it is spread by aphids, so as long as you start with healthy plants from a professional and keep them free of aphids, there should be no issues.
Additionally, it aids in ensuring that all wintertime leaf removal is burned. Plants are kept clean with the aid of good air circulation. When hellebore leaves appear exceedingly spotty, it’s possible that Black Death isn’t the cause—just Black Spot, which is less harmful! Every marked leaf, stem, and bloom should be removed and burned. Plants can occasionally become smut if afflicted sections are removed and burned. Fortunately, there aren’t many pests besides aphids; vine weevil grubs may devour the roots, but I’ve never witnessed it. Stems can be nibbled by slugs, voles, and mice, and an occasional little snail may be spotted in a flower.
Canines consume hellebore?
The idea that nature is benign is widespread, but this couldn’t be further from the truth.
The natural world is full of poisons, many of which can be found in some of our favorite plants, such as the lovely and well-liked hellebores.
Dogs, cats, and horses should not be exposed to the buttercup family member hellebore (Helleborus spp.). Thankfully, they rarely consume it in big quantities due to its unpleasant flavor.

The genus itself makes reference to its toxicity in its name. The words elein, which means to hurt, and borus, which means food, are the origins of the name.
But there’s no denying the aesthetic value they bring to the landscape in the late winter and early spring. And with the right amount of caution, these flowering perennials can be appreciated for many years to come as a part of the landscape.
Do hellebores grow wild?
It’s frequently a nice surprise to see the vivid green petals of this wild flower blooming amid a little coating of snow.
Is it an escaped garden pet? No, not at all. The stinking hellebore is a native plant through and through, even its populations may have been disguised by such variations.
Every component of this wild flower is deadly, and ingesting it will cause vomiting, delirium, and, in the worst case scenario, death. It was once employed as a risky worm treatment. When describing this “treatment,” the 18th-century naturalist Gilbert White said, “Where it killed not the patient, it would undoubtedly kill the worms; but the worst of it is, it will sometimes kill both.”
Identification
Evergreen stinking hellebore has dark green leaves that emerge from a sturdy stalk. The flowers are also green, but they have a softer, yellowish hue and are shaped like drooping cups. There is a prominent purple fringe on the five sepals.
Did you know?
Perhaps the hellebore doesn’t earn the moniker “stinking.” Although crushing the leaves can result in an odor that is sometimes characterized as “beefy,” sniffing the blooms won’t make you want to cover your nose.
Does hellebore grow wild?
One species that is frequently planted in gardens and containers is Helleborus niger, also known as the Christmas rose. However, it was originally a wild species indigenous to Central Europe. It now grows naturally in many more areas, occasionally appearing in forested areas of low-lying mountain ranges. This perennial, which can withstand temperatures as low as 5F (-15C), usually starts to spread in deciduous forests and calcareous terrain.
The Christmas rose is a grassy plant that is poisonous and has stems that can grow up to a foot or a foot and a half tall and are green with scarlet streaks (0.3 to 0.4 m). This plant is known for its leathery, bright green, evergreen leaves and short, blackish rhizomes. There are two to four flowers, each measuring between two and four inches, on each flowering scape (5 to 10 cm). They are frequently single flowers, but they can also emerge in pairs, and their color changes over time from white to pink.
