A perennial evergreen with magnificent leaves, Coral Bells is non-toxic and non-poisonous to both humans and animals. There is no need to be concerned if your pet or child consumes the plant or touches the foliage because the Coral Bells, or Heuchera plant, is harmless in all aspects. The Coral Bells plant is not dangerous, so you can rest easy knowing that you should still keep an eye on your pets and kids around plants, especially if they happen to consume anything they shouldn’t.
Medicinal value of coral bells
All of the identified species in the Heuchera genus are indigenous to a large portion of North America. They have a wide range of various growth habits and can be found on a wide range of habitats, including rocky outcroppings and woodland meadows. Coralbells were not commonly employed until the 1980s, despite being beneficial for numerous landscaping uses. Numerous cultivars with various foliage colors, blooms, and growth styles are now readily available. At Johnson’s Nursery, we make an effort to keep our selection to plant kinds that thrive in the soils and climate of southeast Wisconsin.
Coralbells are also referred to as alumroot, which is a moniker derived from their therapeutic benefits as an anti-inflammatory and painkiller. Johann Heinrich von Heucher, a German botanist and physician, is honored with the genus name Heuchera.
Wildlife Value
Coralbells serve as a valuable nectar supply in Wisconsin even if they are not a key species for wildlife. The tiny blossoms will draw pollinators like hummingbirds, butterflies, and bees.
Pests/Problems
Coralbells don’t have many pest or disease problems, although they can experience frost heaving during the winter. Rust, powdery mildew, and bacterial leaf spot are occasionally found. Weevils and nematodes can potentially harm the plants. The best way to prevent these illnesses, though, is to keep your plants vigorous and in the right location.
Due to their fluffy stems and leaves, coralbells are generally resistant to deer and rabbit damage.
Maintenance Tips
Coralbells are typically hardy plants with minimal issues. Despite tolerating alkaline soils, coralbells are susceptible to rot in areas with inadequate drainage. Composting the soil before planting will help to solve this problem.
If the soil is not moist enough, leaves in full sun may blister. On the other hand, too much moisture in the shadow might cause crown rot. Dividing in the spring once the center has become woody (typically every 3-4 years).
Coralbells in Wisconsin might suffer from frost heave if they are planted incorrectly or are not sufficiently covered. When planting, add compost to the soil and space the seeds evenly. Frost heaving can be avoided by spreading 3–4 inches of fall mulch. Push the top back into the earth to protect the roots if frost heaving is seen.
When the flower stalks have finished blooming, they can be cut off. This could promote a second bloom. Given appropriate protection from mulch and snow cover and a mild winter, the semi-evergreen leaves may maintain their color. In the spring, it’s a good idea to remove any damaged or withered leaves.
Do people eat coral bells?
The majority of heuchera species and cultivars are self-sterile, thus gardeners who desire seed will need to grow many varieties. The seeds are ripe six weeks after pollination, when the seed pods become brown and split apart, and the blooms bloom in the summer. The seed can be gathered and planted right away. In 30 days, the seeds will germinate, and by the fall, the seedlings will be prepared for potting.
Heuchera and x Heucherella can also be separated. Pull separate the rooted offsets and excavate the three-year-old clumps. It might be necessary to pot up the smaller offsets before replanting them in a prepared bed. I’ve successfully done this in both the summer and the winter. The offsets can also be handled as stem cuttings and, as long as they are shielded from desiccation during the rooting process, they will readily root without the use of any rooting hormone. Gardeners may also succeed by carefully taking a leaf from the base of the plant together with a little piece of stem tissue, then rooting the leaf/stem cutting.
Pests and Diseases of Heuchera and x Heucherella
Deer and rabbits usually avoid the astringent (bad-tasting) Heuchera and tiarella leaves. As a result, they make excellent hosta substitutes in areas with high deer pressure. Just keep in mind that a rabid deer or voracious rabbit would eat anything in the dead of winter, including a heuchera.
Insect pests in the garden often have no effect on Heuchera and x Heucherella. Heuchera, however, may occasionally be afflicted by black vine weevils, which bore into the crown and kill the tops (particularly in the Pacific Northwest). The plant will eventually die if left untreated, but systemic pesticides can control black vine weevils. There is no treatment for foliar nematodes, thus prevention is crucial when they do occasionally cause unsightly discolored areas on the leaf. Only purchase plants from nurseries that look for and remove contaminated plants.
Some cultivars will undergo summer dieback in hot, humid gardens because of the fungus sclerotinia. Gardeners should choose varieties that are regarded as hardy in their region. The most crucial preventive strategy is good air circulation, so watch out that other plants don’t outgrow your heuchera.
How to Grow Heuchera and x Heucherella in a Container
In mixed containers, Heuchera and x Heucherella thrive because they like well-drained potting soils with little fertilizer. Water the pots thoroughly in the summer but sparingly in the winter. If the container is not insulated, the pots will require some protection from the chilly winter weather. These plants are perfect for putting together gorgeous combinations because of the leaves they produce and their controlled growth habits.
Landscape Uses of Heuchera and x Heucherella
Garden designers often value the lovely foliage of Heuchera and x Heucherella because it offers a season-long burst of color. Because flowers are frequently transient, colorful foliage is significantly more valuable in garden design than flower color. Heuchera blooms, however, should not be disregarded because they provide the garden, during a portion of the growing season, an open, airy, informal character. The floral display also lasts quite a while if deadheaded. When gardeners include heuchera, they may dependably expect a whole season of purple, bronze, chartreuse, or silver leaves color. Similar to how they utilize hosta, designers can employ heuchera where there is some shadow. Heuchera have a wider variety of foliage and flower colors and the same rosette growth behavior as a small or medium-sized hosta. Heuchera are also deer-resistant and can be employed in gardens that are being dashed by Dancer and blitzed by Blitzen in place of hosta.
Heuchera and x Heucherella pair well with carex, ferns, hosta, and epimedium, among other plants. To create a purple and silver haven, group the purple-leaved heuchera varieties with other purple plants like Japanese maple or purple smoke tree (Cotinus coggygria). Compare the purple-leaved varieties to plants that have complementary colored foliage or flowers, such as yellow-flowered Lysimachia ‘Aurea’, pink-flowered Lychnis, or white-flowered Lychnis (Aloysia virgata). Similarly, combine the aforementioned trees and shrubs with yellow- or bronze-leaved Heuchera to provide a striking color scheme. Use the silver-leaved varieties in formal gardens or night gardens along with other silver or white plants. They complement moon vine, phlox “David,” and hydrangea “Annabelle” beautifully. Utilize cultivars with red, pink, or bronze leaves along with other vibrant hues like red, orange, and yellow to create a riot of vibrant hues.
History and Background of Heuchera and x Heucherella
Heuchera is also known as “alum root” and “coral bells.” The former name alludes to the popular garden species Heuchera sanguinea’s red blossoms. The latter name alludes to the roots’ ability to be utilized as an alternative to alum in the pickling process and their high tannin content. The roots are also used medicinally to shrink tissues in people who have piles, ulcers, and nasal bleeds. The intergeneric hybrid x heucherella, sometimes known as “foamy bells,” was produced by crossing the closely related genera of heuchera with tiarella (the foam flower). Due of their beauty and ease of cultivation, coral bells and foamy bells have become highly popular among fans of native plants.
Native to North America, heuchera can be found from Florida to California in the west to southern Canada in the north. They typically grow in woodland or mountainous (montane) habitats, mainly in cracks or on steep slopes with good drainage. Heucheras can survive in a variety of environments, as evidenced by the fact that I have seen them in the wild on steep outcrops in Tennessee and also in damp seeps in the agave-filled deserts of Arizona.

For their vibrant foliage that lasts from spring to fall, coral bells are prized. The leaves develop into a beautiful mound of foliage. Thankfully, this plant’s entire body is non-toxic! Despite being fairly robust, it might not appreciate being trampled by your dog. To prevent paw traffic and ripped leaves from your dog, consider growing it in a container.
Which flowers can people eat?
I had a variety of roles as a founding worker at Gardener’s Supply over the years. I currently run my own business, which is called Johnnie Brook Creative. A huge vegetable garden, a seasonal greenhouse, a cutting garden, perennial gardens, a rock garden, a shade garden, berry plantings, numerous container plants, and a meadow garden are among the gardens surrounding my Richmond, Vermont, home. The garden is the only place I would rather be. Check out this Garden Gate magazine video interview from January 2021 if you’re interested in learning more.
Remove the center stalk and separate the florets of chive blossoms before adding them to green salads.
Nothing says “gourmet” like adding a few colorful flower petals to a salad, arranging a few Johnny jump-ups on a birthday cake, or sautéing a daylily bud in a stir fry. All kinds of foods can benefit from the color and flavor that edible flowers can bring, especially when you can collect them from from your own garden.
Pick the majority of edible blossoms and eat them uncooked for the finest flavor. Instead of waiting a few days after opening, flowers will taste and appear at their finest straight away.
You can add pickled chive blossoms to bloody marys, martinis, and bagels (with lox and cream cheese).
There are only two crucial considerations for edible flowers: First, not all flowers are edible. In actuality, some flowers can be harmful. In order to assure your safety, stick to the flowers on the list below or conduct adequate research. Avoiding flowers that may have been sprayed with an insecticide, fungicide, or herbicide is the second word of advice. This is rarely a problem because, with the exception of roses, most edible flowers are simple to produce. Unless you have an organic lawn, make sure to remove dandelions from the list.
Consider some of the following for flowers that taste nice and look good:
Alliums. Green salads, potato and pasta salads, and dips are all wonderful when made with chives, leeks, and garlic. To liberate the individual florets from the flower cluster, cut away the central stalk.
Nasturtiums. The flavor of blossoms is spicy, like watercress. In salads or as garnishes, all hues and types are delectable. You can consume leaves as well.
Marigolds. Use the signet marigold’s tiny blossoms, such as the Lemon Gem and Tangerine Gem. Their flowers taste like citrus.
Bring your beverages to a new level. Add edible Johnny Jump-Up Flowers to your favorite beverage by freezing them in ice cube trays.
Johnny jumps up and pansies. These wintergreen-flavored flowers look lovely on cakes and other sweets. Use warmed jelly as a glaze for a jeweled appearance.
Calendula. An edible flower that is simple to cultivate from seed in the garden that is both abundant and easy to grow. Toss the flower’s petals into salads after separating them from the center. Pure yellow, orange, and red are among the color choices. The plants will bloom constantly from early summer to late fall if spent blooms are removed.
Hyssop anise. This edible bloom is for you if you like anise. To add to sweet or savory meals, separate the florets. Alternately, use the entire bouquet as a cheese plate garnish.
Honeysuckle. The flowers provide a lovely touch to salads. The berries are poisonous; don’t use them.
Runt-colored runner beans. Add these vivid red blossoms to salads or cooked vegetables.
Borage. This plant with fuzzy leaves has sky-blue blooms and a mild cucumber flavor. Add to green or fruit salads, or freeze in ice cubes for cool beverages.
Bee venom. The blossoms of this member of the mint family have a mint flavor. From vivid red to purple and pink, the colors are varied.
Chamomile. Small, daisy-like blossoms on English chamomile have an apple-like flavor. Chamomile may not be suitable for you if you have ragweed allergies.
Daylily. Taste-wise, daylily buds and blossoms resemble asparagus. They can be filled, turned into fritters, or used as a garnish. Good for stir-fries as well.
Mint. All flowers in the mint family are edible and have a nice flavor, much like bee balm. Try iced tea with lemon balm or spearmint.
Do I need to deadhead my coral bells?
Although coral bell plants prefer some shade, they may tolerate greater sunlight in colder climates. Give them neutral to slightly acidic soil with a pH of 6.0 to 7.0 that is well-drained, wet, and rich. Some species, like H. sanguinea, cannot grow on soils that are acidic or clayey. Heucheras don’t need much care, other than regular watering during their first year of growth.
Heuchera clumps should be divided as needed or every three to four years. To encourage more blooms, which may last into the summer, deadhead the flowers. Simply trim the stalks after the flowers have completed blooming to encourage the plant to focus more energy on leaf development. If you’d like, trim the foliage back in the early spring so that there won’t be too much new growth.
Problems
These deer-resistant beauties are rarely bothered by pests or illnesses, but coral bells can suffer from leaf scorch in hot, direct sunlight. When the weather changes, keep an eye out for soil heave. This occurs when the ground freezes and thaws, eventually forcing roots up out of the ground. Keeping the plants thoroughly mulched can aid in avoiding this.
Quick Tips for Growing Coral Bells:
- Plant in some shade because scorching sunlight might damage the leaves.
- To prevent roots from being exposed as soil shifts seasonally, mulch well.
- In the fall, trim flower stalks to focus energy on the leaves.
Do coral bells naturally occur in Canada?
Heuchera is a genus of mostly evergreen perennial plants in the Saxifragaceae family that are all indigenous to North America. Alumroot and coral bells are examples of common names. L.
