Around the holidays, when it is offered as a Christmas rose, container-grown hellebore may be seen. These are frequently used for decorations before being let to rot or are simply thrown away, along with other seasonal plants like poinsettia. However, there is no need to allow your potted hellebore to deteriorate. Until you’re ready to plant it outside, you may either keep it in a pot and enjoy it both indoors and outside all year long.
Hellebores require rich, well-drained soil, so make sure to select a pot with drainage holes and plant them in rich, organic potting soil or amend their current soil with compost. Additionally, as hellebore plants dislike being moved, a large container should be selected. Give your plant room to flourish because moving stress can be harmful. Given that the roots typically grow downward, the pot’s depth is very crucial.
Place your potted hellebores where they will receive the most sunlight over the winter and early spring. As the temperature rises, a little shade will be welcome. In the winter, hellebore prefers cooler temperatures, so make sure it receives sun without getting too hot. Find an elevated spot for your container-grown hellebore so you can completely enjoy it. The flowers have a tendency to fall downward.
Hellebore thrives when grown in the ground outside, but if you’re short on space or just want to enjoy these wonderful blossoms indoors, you should be able to make it happy in a container.
Hellebores should be pruned back after flowering, right?
Before the flower pods split, I always remove all of the flower stems. Last but not least, it’s common advice to divide your hardy perennials every three years and replant the healthiest pieces in better soil.
How are hellebores maintained in bloom?
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.
How should I maintain my 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.
What should you do with hellebores in pots in the summer?
How to care for fresh hellebore plants once you get them home from our nursery or when they arrive at your house via our mail order service is a question we are asked frequently. We believe the following guidance will provide all the information you require:
Please take away all the packaging from surrounding your hellebore and place the plant outside in a wind- and weather-protected location. This holds true year-round, even in the winter.
If the compost is dry, check it and place the plant in a saucer of water for an hour, making sure to take the saucer out once the hour is up.
Hellebores are extremely hardy plants that are happier in the ground than they are left standing in their pots, so plant as soon as you can.
It’s necessary to remove flower stamens and petals that have fallen into the plant if planting must be postponed due to cold or soggy ground conditions. This should be done every day up until planting out as it will help prevent the growth of grey mold, also known as botrytis, around the base of the flower stems or inside the crown in moist winter conditions. If there are any fungal issues, spray with a fungicide as soon as they show.
Even when planted, if your hellebore does become iced and rests flat, it will recover as the weather warms.
As long as the soil is not too dry or flooded, hellebores are quite tolerant and will grow in most soils, ranging from slightly acidic to slightly alkaline. In the summer, they can endure dryer circumstances as long as there is some shade, but too much shade all year can cause fewer blossoms. They thrive best when surrounded by deciduous shrubs and trees that will offer them with plenty of light in the winter and spring and some pleasant shade in the summer. They are resilient in the UK, with just a few exceptions, however they demand a sheltered location away from chilly winds. Hellebores will benefit from better drainage and easier access to the flowers if you put them on a sloped bed.
Hellebores have deep roots and require a lot of nourishment to flower at their best. Dig your soil as thoroughly as you can, then add lots of humus, such as leaf mould, well-rotted manure, leftover mushroom compost, or garden compost. When the ground is frozen or flooded, avoid preparing the soil; wait until the situation improves before planting.
Before planting, give your hellebore a good drink from below if it’s dry. Create a hole that is broader and deeper than the pot. Remove the hellebore carefully from its pot, then sprinkle If desired, root-grow mycorrhizal fungi onto the root before planting it at the same depth as in the pot and compacting the soil once more. There is no need to pluck out the roots because doing so harms their fibrous root system unnecessarily. After planting, thoroughly water.
In July/August, while the flower buds for the following year are forming, and again in late December, spread a humus mulch annually. Mulch shouldn’t be inserted into the plant’s crown as this could lead to the decay of the buds. Work in some blood, fish, and bone fertilizer and calcified seaweed fertilizer in the spring. Keep in mind to water your newly planted hellebores frequently for the first year. If you don’t need seed, remove the old, faded flower stalks around March or April to promote the growth of the new growth for the next year. In order to prevent greenflies, you can spray an insecticide and fungicide on occasion. You should also keep an eye out for slugs and snails on flower stems, new leaves, and flower buds, and treat them as necessary.
Helleborus x hybridus Ashwood Garden Hybrid should have all of its foliage cut back to the stems.
Hybridus H. Garden of Ashwood Remove all foliage from hybrids and deciduous species’ bases in late December or early January. This lowers the chance that any pests or diseases from the previous season would spread to the following season’s growth.
Only remove damaged or diseased leaf when necessary to tidy up evergreen species and interspecies hybrids (such as the Rodney Davey Marbled Group, H. x ericsmithii, H. x sternii, H. argutifolius, and H. foetidus) in late Autumn. Remove old flower stalks and leaves back to the root in late spring to reveal new, youthful growth there.
H. niger: After flowering, simply trim the damaged or diseased leaves and old flower stems as needed to keep the plant looking clean.
Hellebores are naturally deep-rooted plants, so choose a container with a decent depth and a broader top than base so you can remove the plant with ease when it has to be replanted. To avoid over-potting the plant and the possibility of it being soaked in damp unused compost, choose a container that is slightly larger than the present pot.
Use a high-quality compost, ideally one that is loam-based, like John Innes No 2 with additional grit for drainage. Put the container’s feet on pots. They require regular watering and feeding with a strong potash fertilizer like Chempak No 4 in the summer because they are hungry plants. Place the container where you can see it from the house while it is in bloom, then transfer it to a semi-shaded location in the summer. Repot plants every two years with new compost, or better yet, plant them outside in the garden.
You can uproot and divide your plant in September if you want to move it or it gets too huge. It is important to properly dig up the entire plant. When splitting, the huge root system is much easier to manage if all the soil is removed before cutting the root ball into single crowns using a knife or small saw. Replant the crowns in prepared soil and maintain shade and moisture, but be aware that it can take some time for the new divisions to recuperate.
