About Growing Perennial Coral Bells in Your Home Flower Garden

Native to the woods and prairies of North America, perennial Coral Bell plants look nice in many settings. Most gardeners and homeowners grow them for their bright and colorful foliage. They look great in partially shaded areas of your yard where the selection of plants is more limited. This perennial plant has evergreen leaves, in a variety of foliage colors, with scalloped edges. And, growing Coral Bells flowers is easy. Established plants are basically maintenance-free.

There are hundreds of varieties groups into approximately 50 species. 1/2-inch bell-shaped flowers bloom in the spring atop tall, thin spikes. 

Hummingbirds are attracted to this flower.  

Coral Bell plants look good in shade gardens, rock gardens, as border edgings, and for ground cover. Try them in containers, on your patio or deck.

Medicinal Applicatons

The roots are used to shrink body tissue for nose bleeds, sore throats, ulcers, and hemorrhoids.

Coral Bells Plant Propagation

The plants are grown from seed. Sow Coral Bells seeds directly into your flower garden or started indoors for transplanting later.

If planting outdoors, sow Coral Bell seeds after the soil has begun to warm in the spring. Also, make sure to mark the planting site, as the seeds take a long time to germinate.

Due to the long germination time, we recommend an indoor start. Sow seeds indoors 6-8 weeks before the last frost in your area. This will allow you to better space the plants in your flower bed. 

The plants can also be propagated by dividing the clumps in the spring or the fall.

Plant Spacing: The final spacing in your garden should be one to two feet. Obviously, give larger varieties the most spcace.

Day to Germination: The seeds are slow to germinate. They take over 2 weeks.

Light Requirements

In cooler regions, grow Coral Bells plants in full sun. However, for most areas, filtered sun to partial shade is best. Too much direct sun can cause the flower colors to fade. 

Also, too much shade, especially in humid conditions, can cause fungal diseases.

How to Grow Perennial Coral Bells Flower Plants

As stated above, growing Coral Bells flowers is easy.

The plants grow best in full sun to partial shade. They tolerate a variety of soils but will do best in rich soil.

Add a general-purpose fertilizer once a month. We also recommend that you add a thick layer of compost or mulch, to feed the plants, keep weeds down, and retain moisture.

Even soil moisture over the growing period is best. Keep plants watered, especially in the first year, and during dry periods.

After the first bloom in spring, deadhead spent blooms. This will promote a second bloom for the plants.

Pruning Coral Bell Plants

Remove any dead, sickly or diseased branches and leaves. Also, thinning the leaves out a little helps to minimize the risk of plant disease.

Insects and Plant Disease

Coral Bells are resistant to most insects. Fugal disease can occur in damp weather.

If insect or disease problems occur, treat early with organic or chemical insect repellents and fungicides.

Overwintering Coral Bell Plants

As a perennial, the plants should overwinter with few, if any problems. 

In colder regions, the roots can heave out of the soil. To avoid this problem, apply a thick layer of mulch around the base of the plants.
