I inherited a yard with a sizable collection of hellebores ten years ago; they ranged from milky white to yellow, pink with flecks, to the deepest burgundy. They flourish in this soggy Welsh garden, which receives plenty of summer light but a lot of winter gloom.
Hellebores put on a fantastic display in the late winter and early spring, but their enormous, spreading leaves do make them a big space-eater in the summer. It is advisable to perform a hellebore “audit” to make sure they are making a profit for this reason.
How to handle hellebores
The greatest season for a hellebore audit is spring, when the blooms are in full bloom. Think about where you have your hellebores planted. Additionally, consider whether the color is appropriate. Perhaps the borders are gradually becoming a neutral pink color. The plant Helleborus orientalis is promiscuous. It produces a large number of hybrid seedlings since it produces large amounts of seed and doesn’t care who it crosses with.
The prized double dark beauty I had spotted in Tyntesfield a few years ago has finally taken up residence outside my basement window, where I can enjoy the multi-petalled silk blossoms while doing the dishes. There are numerous seedlings all around it that could potentially crowd out the mother plant. It’s tough to tell if these are kids with the dark double gene or if they are yet another mid pink hybrid from a cross with a controlling neighbor.
The solution won’t be known for several years because the children won’t blossom until they are considerably older. So now is the time to pay for them, pot them up, and give them to your neighbors who are willing to take a chance.
How to divide hellebores
There are alternative, more expedient ways to add more hellebores to your collection while still knowing exactly what you are getting. If you are careful, this family does split fairly well. Just after flowering is an excellent time to do this, while you can still clearly recall what color they are!
I always remove the leaves from mine in the dead of winter to highlight the blossoms when they appear and reduce the possibility of the dreaded black spot. You must be careful not to injure them when you raise and split them in April since they are just starting to put out new leaves.
Hellebores are best separated with two hand forks inserted into their crowns because they have a lot of thick, fibrous roots. Make sure each part is sprouting some fresh leaves. Depending on the size of the clump you dig up, you could be able to double, treble, or even quadruple your supply.
I favor getting these divisions back into the border immediately where you see a hole that has to be filled in rather than patching them up. Place them where you can admire the flowers—perhaps on a bank, by some steps, or outside that basement window—a true sign of spring as we stay indoors during the bitterly cold winter.
Can you divide hellebore plants?
The best moment to divide a hellebore is when you are already moving it, even though you should only move them when required. In September or October is the ideal time to transplant and/or divide hellebores. The optimal time to divide hellebores is just before their autumn root growth spurt, which occurs about this time each year. This enables the rapid establishment of new roots in the plants that have just been divided.
When transferring hellebores, you should dig up the entire plant in an 8-inch-deep circle that is six inches from the outermost leaves if you want to divide the plants. Once it is freed, raise the plant off the ground, wash the crown to remove any dirt, and then use a sharp knife to cut between the growth buds so you can see what you are doing. The plant will heal faster if you leave at least three buds in each division. A least of one bud, ideally two or three, some woody rhizome tissue, and some developing roots are required for each new division. The next step is to plant each tiny transplant with lots of organic debris in a spot that is somewhat shaded and to water it well.
After that, mulch the transplants with a layer of compost or leaf mulch and keep watering them until they are established.
When can Hellebore plants be divided?
Typically, hellebores live a lengthy life. They remain healthy and flower freely because to the regular mulching. It is recommended to transplant or divide a hellebore in September or October even though this is not typically necessary for the plant’s health. The best way to divide a plant is to dig it up completely, wash the crown to remove any remaining dirt so you can see what you’re doing, and then cut between the growth buds with a sharp knife. The plant will heal faster if you leave at least three buds in each division.
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.
How well do hellebores transplant?
There are around 20 plant species in the genus Hellebore. Lenten rose and Christmas rose are the two most popular varieties. The plants are wonderful specimens for a shady area in the garden and generally bloom in late winter to early spring. Although it is not necessary, dividing hellebore plants can improve older plants’ flowering. Hellebores can be easily propagated by division as well as by repotting the many young plants that the plant quickly produces each year.
Are hellebores pruned back in the fall?
Early spring or late winter, just as the new growth starts to show, is the perfect time to prune a hellebore plant. This new growth ought to emerge from the earth as little stalks. These stalks ought to still be encircled by a ring of the large leaves from the previous year. The old leaves may very likely have been harmed by the winter’s cold and appear a little worn-down.
These old leaves can be removed as soon as the new growth develops by chopping them off at the base. You don’t need to prune your older foliage as long as it is healthy and undamaged, but once the new growth begins to leaf out, you’ll need to make room for it by pruning the older growth. If you wait too long to remove the old growth, it will tangle up with the new growth and be much more difficult to remove.
Hellebores can be eaten by snails and slugs as well, and the thick foliage provides them with wet, hidden hiding places.
Do hellebores like shade or the sun?
- 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.
What plants thrive next to hellebores?
Annuals are wonderful, lovely, and vibrant. What about planting partners for perennials? That is the key to a consistent wave of color and greenery that returns to the garden year after year.
Use these
Astilbe
some of the “Astilbe (Astilbe spp.) is a shade-loving perennial that is content to be left on its own in the garden to spread and divide, joining the set it and forget it crowd of hellebore planting partners.
I think astilbe ought to be the “Hellebores are occasionally employed as a strong anchor as a filler plant.
In order to prevent the astilbe from steadily encroaching on the hellebore’s territory and taking over, make sure to leave some space between the two plants.
Do you remove every leaf from hellebores?
The seeds frequently fall back into the clump, where they may eventually germinate and blossom, lessening the influence of the parent plant by producing weaker offspring. Before the flower pods split, I always remove all of the flower stems.
Hellebore spreads swiftly, or not?
Depending on the particular plant, hellebores typically spread out between one and three feet. They require prompt maintenance to prevent drying out and suffering because they have the potential to multiply up to nearly a dozen divided plants.
Because they spill Hellebore sprouts into the ground, which are essential to the entire spreading process, hellebores frequently spread rather quickly under various circumstances. Once the root system has created, you shouldn’t try to divide or transplant them. They dislike being relocated. Source.
These distinctive and colorful Hellebores, often known as “Lenten Rose” or “Christmas Rose,” are well renowned for being quite sustainable and hardy across a variety of climates and regions. Without a shadow of a doubt, they will thrive under conditions of average climatic conditions and even minimal upkeep.
What location is ideal for planting hellebores?
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.
Is it safe to handle hellebore?
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.
