Hellebores with winter flowers have gained a lot of popularity recently. The Lenten rose (Helleborus x hybridus), one variety, won the Perennial Plant Association’s 2005 Perennial Plant of the Year award. In the dead of winter, this hellebore and its close relatives (the Corsican hellebore, the Christmas rose, and other hellebores) bloom with lovely flowers. Most are incredibly attractive, easy to cultivate, and resistant to harsh environments. They are therefore suddenly appearing in gardens all throughout the city.
However, owning these plants comes with a tiny bit of maintenance that over time dramatically improves the tidiness of the plants and maintains them strong and attractive.
To prune the leaves and blooming stems from the previous year is a straightforward procedure.
Cut the foliage from the previous year’s Lenten rose (Helleborus x hybridus) down to the base as the flowers start to appear in January or early February. This enhances the visibility of the flowers while also preventing the transmission of a fungal disease from the old (if you decide to leave them on) to the new leaves. Therefore, if you were “in the know,” you would have removed the old leaves at that time. If not, you can do it right away!
Despite blooming in late December or early January, the Christmas rose (H. niger) has lovely blossoms for months. From February through April, trim old leaves and flowering stems as new growth appears and the blooms start to fade. or whenever you feel like doing it. Hellebore forgiveness is astounding.
If you haven’t already, you should trim back the old flower stalks of the bear’s claw hellebore (Helleborus foetidus), also known as the stinking hellebore.
As the flowering season for these late varieties of hellebores comes to a close, now is the perfect time to trim back the foliage on all other varieties. The Corsican hellebore (H. argutifolius) and hybrid hellebores like H. x sternii are examples of late forms.
How to prune a hellebore is as follows:
Grab your clippers and trim the bases of all the tough, older leaves and blooming stalks. Keep the fragile, fresh foliage that is developing from the plant’s heart; it will eventually replace the harsh outer stems and leaves that you removed. Feel it to determine which is which if in question. The aged leaf has a rough, leathery feel to it. The fresh growth is malleable and delicate! If the fresh greenery appears a bit wilted, don’t panic. It has been expanding under the cover of the previous vegetation. It only needs a few days in the wind, rain, and sun to become more resilient.
In order for the seeds to ripen, you can also leave some dried-out blossoms on the plant. You frequently end up with a tiny forest of seedlings underneath the mother plant the following spring, especially with the Lenten rose. Dig them up and distribute them throughout your garden or with friends.
The plant stays neater when the old stems and leaves are removed. Because they get overcrowded and are more susceptible to illness and aphid infestation, it also maintains hellebores healthy. Your plant will therefore look better and flower better the following winter if you give it a brief spring cleaning.
Must I get rid of the hellebore leaves?
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.
When should the leaves of a hellebore be reduced?
The optimal time to prune stemless varieties like Helleborushybridus is in November, but it’s not too late; simply clip the old leaves off at the base. More severe is the so-called “hellebore black death.” This virus disease has no known treatment, so infected plants should be removed and killed.
Hellebores should be pruned back after flowering, right?
As the flower buds begin to appear, late winter or early spring, depending on your growth zone, is a good time to remove the old, dead leaves from the plant.
You run the risk of destroying the lovely blooms if you wait until the plant has fully bloomed.
Older, decomposing leaves can also serve as a breeding ground for bacteria and fungal spores that can harm surrounding plants, including lenten rose bushes.
As soon as you see any sick growth, you should trim it to prevent it from spreading to nearby plants.
Following pruning, fresh leaves will emerge from the core of the plant and spread out as they get bigger.
Hellebore pruning is a simple process, but you’ll need the correct equipment. Use razor-sharp bypass pruners at all times.
Additionally, hellebores have tiny thorns, thus it is advised to use sturdy gardening gloves.
Continue to remove any broken leaves as the growing season goes on to give the plant a neater appearance.
Hellebores are forgiving plants, unlike some plants that are quite particular about when you should prune them. It won’t care if you keep it clean all year round!
Although hellebores are said to bloom in the late winter and early spring, they are evergreen all year round, so I also find myself cutting them in the summer.
Deadheading hellebores flowers
I frequently get the inquiry, “Should I deadhead hellebores? The simple answer is yes, but it will be more enjoyable to learn the lengthy answer.
You’ll be surprised by how long a hellebore plant’s blossoms last. Some of mine have been in bloom for months. But everything nice has an end.
It’s simple to deadhead hellebores. Simply cut off the old flower stems when they begin to wilt. Cut them back to the plant’s root system.
The Bear’s Foot Hellebore (H. foetidus), commonly referred to as “stinking hellebore,” is an exception. You should leave the stems on the plant since they contain the bloom buds for the following season.
By deadheading their blossoms, hellebores can focus their resources on developing new blooms rather than trying to preserve their fading flowers.
Some Hellebore plants produce flower clusters that tower over the rest of the plants. On mature plants, these stems have a tendency to become quite heavy and droopy.
Deadheading hellebores with all of their stems is a good idea when their tips become too straggly.
Why do the leaves of hellebore become brown?
A prevalent fungus that affects many hellebore species is hellebore leaf spot. Round, lifeless, brown patches appear once it infects leaves and stems.
Can you prune hellebore plants in the summer?
Hellebore pruning The beginning of fresh growth is the ideal time to prune hellebores. Late winter or early spring are the typical times for this to occur. You should eliminate any existing growth to make room for new growth when you see it.
How should hellebores be cared for after blooming?
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.
Why are the leaves on my hellebore becoming black?
The illness that produces stunting, distortion, and black streaking and netting patterns on the leaves is known among hellebore producers as “black death.” It is most likely brought on by the Helleborus net necrosis virus (HeNNV).
Why do my hellebores fail to thrive?
Those leaves are not receiving any water. So either the soil is excessively dry or the roots have been lost. If watering doesn’t help, you could dig it up and check what’s going on underneath. If giving it a very good drink (a bucket full) doesn’t help, it should perk up within 48 hours.
I wouldn’t suggest pruning back hellebores. The roots must get energy from the leaves in order to grow the leaves and blossoms for the following year. For one year, you could get away with it, but not continuously.
How can hellebores be kept from drooping?
Have six years passed since I published my first blog entry on how to gather hellebores? Time flies. In order to ensure that everyone is getting the most out of their priceless hellebores, I thought it would be a good idea to dust off an old tutorial as the Northeastern region is about to enter another harvest season for hellebores. They truly make spring bouquets such a delight to have!
How to Harvest Hellebores
Around 2012, hellebores rose to popularity in floral design, and they have remained so ever since, especially among farmer florists who are looking for a robust bloom for their early-spring creative work. We’re all still in need of some color in our life, and hellebores are one of the first flowers to blossom each spring, frequently even before the snow has melted. Their delectable hues and patterns contrast nicely with their endearing nodding heads. Oh, how enticing it is to cut and place in a vase! But it pays to wait and avoid cutting these gorgeous garden flowers too soon!
Back in 2004, when I moved into my first house in Philadelphia, I first fell in love with hellebores as a decorative plant for my small shade garden. But soon I was cutting them to bring inside for enjoyment. Who wants to adorn them outside in the chilly weather, after all? In 2019, my collection of hellebore plants has grown to well over 200 plants (and counting!) and likely includes nearly as many types.
I’ll let you in on a little secret before you ask me which varieties are ideal for cutting: buy your hellebore plants in the spring while they are actively blooming in their containers at the nursery so you can see how long the flower stems are and if their heads face up or down. Even a designated cultivar of hellebore, which is infamous for crossbreeding, may exhibit various characteristics from plant to plant. Therefore, I believe it is better to consider your purchase before making these overpriced pretties. If I had to pick just one kind, I’d say the Brandywine series, as I actually have quite a few of those plants.
Currently, as a flower grower, I usually get inquiries on how to create hellebores “final in the vase They are used by so many designers, but they all quickly fail. There are some techniques available for “post-harvest remedies that could aid in preventing wilting. Others employ a chemical rapid hydrating solution, others shove a pin up the stem, and still others immerse them in boiling water. Some folks also combine all three. According to my observations, there is just one surefire method to obtain long-lasting hellebores.
Harvest hellebores when they are mature.
I’m done now. It’s that easy. When harvested at their mature stage, hellebores won’t wilt.
The prominent petals of a hellebore “bloom” are actually something called sepals rather than true petals. They protect the flower portion, which is located in the center of the showy sepals and consists of a group of delicately textured stamens and a few tiny, inconsequential petals (in the photo above, the ruffled green at the center are the petals). The stamens and petals fall off after fertilization, and a seed pod begins to develop in the center of the sepals.
Using hellebores that already have their seed pods produced is the best way to ensure that they last in floral arrangements. The hellebore will be more robust the more developed the seed pod is. This is because the sepals resist withering by becoming stiff and waxy as the seed pod grows. A mature hellebore can actually survive beautifully for a day or longer without water. They work well for hair flowers and boutonnieres.
Can you tell which hellebore is almost ready for harvest and which one isn’t?
Another tip I’ve picked up over the years is to use a sharp knife to cut my hellebore stems rather than scissors or snips. In contrast to snips, the knife creates a clean cut that does not crush the cells in the delicate hellebore stem. To assist open up additional water-absorbing tissue, I’ll also cut an inch-long split up the middle of a stem if the bottom of the stem is very thick. If the seed pods are fully grown, this step is not necessary, but occasionally, when I’m pressed for time to gather some blooms that are a little on the immature side for a specific wedding or event, I’ll go the extra mile, just to be safe.
Go place an order for some hellebores from my favorite vendor, North Creek Nurseries, now that I’ve got you all psyched about growing them for cutting.
