The first hellebore (Helleborus) blossoms appear in December, and thanks to the several varieties I’ve added to my garden over the years, a succession of blooms will last into March.
Although the Helleborus orientalis, or Lenten rose, is well known to many gardeners for its vibrant range of hues, it is the “old-fashioned species” rather than the modern hybrids that capture my interest. The majority of plants have significantly sturdier foliage that is appealing all year round. The gaudy Lenten rose is preferred in magazine stories. Naturally, this hellebore has the greatest availability in the retail nursery industry.
I looked for alternative species after learning that the many deer in my garden will not consume the Helleborus orientalis. I’ve added a few to my garden over the years and have discovered them to be sturdy, deer-free evergreen accents. Now I may enjoy important foliage and weeks of colorful flowers throughout the year.
The lengthy bloom of the bear’s foot hellebore (Helleborus foetidus) has just started. When the green flowers open and turn chartreuse, they will eventually become the center of attention in my entry garden. Each cup-shaped bloom’s margin has dark crimson patterns that are visible only under close inspection. The flower cluster grows at the very top of the sturdy central stalk.
Helleborus foetidus has delicate-looking dark green leaves that are neatly split. This two-foot-tall evergreen perennial gives the winter garden more vigor. This hellebore has withstood the highest summer solar exposure of any hellebore.
Bear’s foot hellebore will flourish if provided with some afternoon shade and sporadic irrigation. It’s one of the few consistent perennials I’ve found growing next to a deciduous tree with shallow roots. One plant will produce enough volunteers to increase the planting and spread to friends because it easily seeds.
The Corsican hellebore (Helleborus argutifolius, H. corsicus), which is comparable in height to H. foetidus and has similar cultural requirements, will bloom next. It is arguably the sunniest of all the hellebores, but in our Sierra foothill environment, it looks even prettier with a little shelter from the strong afternoon summer sun. The leaflets’ finely serrated edges do not encourage contact because the foliage is broader. Flowers are long-lasting through late winter and have a light green color.
At Emerisa Gardens in the vicinity of Santa Rosa, I came across Helleborus x sternii, a very pretty hellebore. I made the decision to attempt one in my garden after becoming mesmerized by the robust foliage’s unmistakably silvery-blue sheen. It took longer to grow than the other hellebores, but the wait was worthwhile. Even on overcast days, the leaves of this plant catch just a hint of sunlight, making it a striking year-round evergreen accent.
More than the other hellebores, Helleborus X sternii grows numerous stems, giving it the appearance of a tiny evergreen shrub. A excellent exposure is in some partial shade. The leaves did not burn when I tested it there where it gets some strong afternoon sun. Flower color is a pale green.
All hellebores share the ability to rapidly self-sow when conditions are favorable. Top treat the space around the plant with a half-inch of compost as each species starts to bloom. Since the flowers take weeks to develop from the initial bud to seed stage, there’s no rush with this garden task.
A “bed for the seed to drop into, the compost creates a favorable environment for germination. Before seedlings appear, a whole year is likely to pass. A crucial component of the process is stratification, which the winter’s freezing temperatures offer. If the parent plants are surrounded by a deciduous tree with enormous leaves, remove the leaves in the fall to prevent concealing the spring-emerging seedlings. Each hellebore will be shielded from heavy rains by a second light layer of compost.
Hellebores are extremely water-efficient plants, flourishing in arid environments with shallow tree roots. They bloom from December to March and are among the best evergreen and deer-resistant plants for shade and semi-shade gardening.
Does deer consume hellebore?
HelleborusHellebore They retain their leaves throughout the winter and signal the end of the season with blooms in the early spring or even in the late winter. They are extremely resistant to deer since they are toxic.
What creatures consume hellebore?
In general, hellebore plants are strong and robust, and they are not particularly prone to being harmed by pests. Some insects do, however, consume hellebores.
Aphids are one to be aware of. The foliage of hellebore can be eaten by them. However, they pose little threat to hellebores as pests. Just use hose water to rinse them off.
Leaf miners are a different species of bug that consume hellebores. These insects create “mined out serpentine regions” by digging through the leaf surface. That doesn’t make the plants more attractive but it also doesn’t kill them. Trim and burn any damaged foliage.
Hellebore leaf holes can be consumed by slugs. At night, remove these pests from hellebore plants. As an alternative, lure them with cornmeal or beer-baited traps.
Along with other insects, vine weevils consume hellebores. They have yellow markings on a black background. You should manually remove them from the plant.
Rodents, deer, or rabbits are not likely to be a problem for hellebores. Animals won’t touch the plant because it is harmful in all sections.
Fungal Hellebore Plant Pests
You must keep an eye out for fungal hellebore pest issues in addition to the insects that consume hellebores. These include hellebore leaf spot and downy mildew.
A grey or white powder that develops on the leaves, stems, or even flowers is a telltale sign of downy mildew. Every two weeks, use sulfur or a general insecticide.
Coniothyrium hellebori is the fungus that causes hellebore leaf spot. It multiplies in wet environments. Your plant may have been affected if you notice any dark, round blemishes on the leaf. To remove and destroy all contaminated leaves, proceed swiftly. Afterward, spray with a Bordeaux mixture once a month to stop the fungus from causing further harm.
Botrytis, a virus that flourishes in cool, moist environments, is another fungus that causes difficulties with hellebores. You may spot it by the plant’s gray moldy exterior. Eliminate all infected plant life. Then, water during the day and keep water off the plants to prevent the spread of illness.
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.
What devoured my hellebores?
Beautiful floral plants called hellebores blossom in the early spring or even in the dead of winter. Since the majority of plant species are evergreens, it can occasionally be unattractive to have last year’s growth still there when the new spring foliage emerges.
Are hydrangeas immune to deer?
Are hydrangeas immune to deer? The quick response is no. Deer enjoy nibbling on the delicate tips, flowers, and leaves of hydrangeas. However, there are methods that hydrangea enthusiasts like me can employ to lessen deer damage. Plant the toughest hydrangea varieties first. Next, put up a fence to prevent deer from getting near your plants. To deter grazing, spritz deer repellant. To discover more about cultivating hydrangeas in a deer-populated area, continue reading.
Do rabbits or deer consume hellebores?
In the early spring, rabbits will eat early blooming treats like crocuses, so what can a flower-less gardener do? Fortunately, the hellebore, sometimes known as the Christmas rose, is a very resilient and early-blooming substitute that rabbits stay away from. Many traditional hellebores have demure, downward-facing blooms that are murky colors of mild cream, green, or reddish brown in the spring, but more recent hybrid varieties, like ‘Amber Gem,’ have larger blooms with ruffled petals that are vivid pink or gold in color.
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.
Are hellebores immune to slugs?
Slugs and snails are the misery of many gardeners’ existences; they destroy many of your favorite plants by munching on tender young shoots and seedlings. However, the Royal Horticultural Society (RHS) recently declared that slugs will no longer be considered pests but rather an essential component of the garden ecology.
Hostas, for instance, are pure slug magnets. Even if you use copper tape, grit, wheat bran, beer, and countless other magical repellents to attempt to keep the pests away, eventually those pesky little creatures will turn your priceless funkia leaves to lace.
I don’t believe I’ve ever participated in a Gardener’s Question Time without a slug-related question because slugs and snails have a reputation for causing damage.
However, there are many plants that they do not consume, so if they become a problem, the easy solution is to produce more things that are off their menu.
The choice of slug-proof plants is frequently a matter of common sense. It is less probable that leaves and stems will be used as slug food if they are felty, hairy, dusty, or harsh. Molluscs rarely destroy silver foliage plants like lavender, santolina, helichrysum, and teucrium.
It makes sense that these have leaves that are both scented and repulsive. Santolina ‘Lemon Fizz,’ a variety with golden leaves, provides a vibrant contrast to the plant’s typical silver foliage.
Shrubs won’t be discussed because they aren’t often slug and snail targets. They are not enticing to eat or climb over because of their woody stems.
Perennials
Keep the fragrant component in mind when choosing perennials. Typically, plants with oil-rich foliage are more resilient. For instance, consider herbaceous geraniums. Snails and slugs may conceal themselves among the leaves, but they do not consume them.
Even in the shaded areas that slugs and snails adore, the early flowering Geranium phaeum thrives, but they won’t eat its leaves or blooms.
Herbs
Slugs have no chance of harming marjoram, Origanum vulgare, or any of its variations. It frequently seeds profusely in light, dry soils, yet there is no doubting its usefulness as a wanderer in the border and as a culinary herb.
Early in the growing season, when the leaves are young and vibrant, and in late summer, when the plants are in bloom and the leaves become a mellow gold, the golden-leaved variety is very appealing.
Foxgloves
Since foxgloves are poisonous, even the most voracious pests like deer and rabbits avoid them. The wild foxglove, Digitalis purpurea, is a biennial plant, meaning that it grows one year, blooms, produces seeds, and then dies the next year.
Some foxgloves, like Digitalis ferruginea, are however transient perennials. With its tall spikes of densely packed coppery flowers, this is an even more appealing garden plant; you’ll adore it but slugs and snails will loathe it.
Euphorbias
The spurges, sometimes known as euphorbias, are included in this group. Gardeners should avoid bringing their skin in contact with the milky, irritating sap that is present on their stems and leaves. They are therefore pest-repellent as a result.
They are also slug-proof and, once more, deer and rabbit proof. The stunning plant Euphorbia characias, which is towering and edifice-like, will seed on sandy, well-drained soils. Plants can exist for many years and each season, new stems emerge from their woody bases.
This particular euphorbia is a perennial evergreen that resembles a shrub in many aspects. In late winter and early spring, the lime green “flowers” at the stem tips are breathtaking.
Penstemons
Penstemons and other evergreen plants with woody stems have some similarities. But since slugs and snails are rumored to eat them in some gardens, I’m not going to suggest these as slug-proof.
However, I will suggest evergreen hellebores like Helleborus argutifolius and Helleborus x ericsmithii. These feature hardy flowers that are held in huge clusters above the foliage and hardy foliage. These appear to be unpleasant to molluscs and are transported safely.
Additionally, they thrive in the shade, so they will brave the hiding places of our slick adversaries.
Pulmonarias
In this case, too, pulmonarias, the lungworts withstand attack but the hostas are easily eaten. The advantages of pulmonarias include early blooming and nicely patterned leaves that are occasionally speckled or covered with silver. As the season goes on, the leaf can start to appear a little ragged, but it rarely looks as bad in the garden as a hosta that has been attacked by slugs.
Seedums
Sedums are vital for late summer color and their powerful, bold plant shapes in sunny areas of the garden. The most popular and well-known sedum varieties are Sedum spectabile and its cultivars.
The fleshy growth buds that are grouped on the soil in the early spring may occasionally be nibbled at by slugs, but they don’t seem to cause too much harm as the stems develop. If there is damage, cover the plant’s crown with coarse grit so that slugs won’t want to cross it and the plant will benefit from the drier soil.
In the majority of gardens, the stalks and faded flowerheads that become dark brown throughout the winter still seem lovely. In others, they appear to fall over as the stems lose their support. Late winter presents a special issue with this.
Reduce the stems by a third to a half in late April to avoid this. Then they will branch, but they will get shorter and stay upright. Despite the smaller flowerheads, the overall impression ought to be more appealing.
Aquilegia
The aquilegia, often known as columbine, is one of our favorite cottage garden plants and a fantastic slug-proof subject. There are numerous varieties, and they do have a propensity to hybridize and spread by seed; all of which adds to their allure.
Some of the most showy types are those with bigger outer petals and lengthy spurs; keep an eye out for the “State” series. Aquilegias make excellent “drifters,” or plants you can wedge between other perennials and shrubs to give the planter a bit of height thanks to their long flower stems and nodding blooms.
Agastache
As I previously stated, anything with fragrant leaf is a wonderful option for a slug-resistant plant. The enormous hyssop, Agastache foeniculum, is gaining popularity as a border perennial and for use in prairie designs with grasses.
There are several wonderful variants with flowers that are bigger and more impressive than the species. Their draw is their ability to draw bees, butterflies, and other pollinators; an added benefit is that they repel slugs and snails.
Knautia, eryngium, and nepeta are some other perennials that I’ve discovered to be largely mollusk resistant.
